Bright coloured Co (II) and Ni (II) complexes of an azo ligand were synthesized. This ligand was previously synthesized from the coupling reaction between 4,5-diphenyl imidazole and 4,4-diaminodiphenylmethane in 1:2 molar ratio (4,4-diaminodiphenylmethane and 4,5-diphenyl imidazole). The synthesis process of the complexes involved the reflux reaction between the azo ligand with both metal salts. The synthesized complexes were characterized by FTIR, UV.-Visible, molar conductivity and atomic absorption. From the obtained characteristic data of the FTIR spectra, the coordination between the two metals and the azo ligand occurs by the coordination with the nitrogen atom of the azo group and one of the nitrogen atoms in the imidazole both rings. The molar conductivity test confirm the non- electrolytic nature of both complexes, while the atomic absorption agrees with the expected complexes formula. Therefore, the octahedral structure for the two complexes is suggested. The anti-corrosion activity of the synthesized compounds were investigated under two temperatures (298 and 308 K) with 0.03 gm of each compound was tested. According to the results cobalt (II) complex shows a better anti-corrosion activity (93%) in comparison with the ligand and nickel (II) complex.

In present study, a solvent extraction experiment has been done to separate cobalt from the nickel sulfate solution by using 2-ethythexyl phosponic acid mono-2-ethylhexyl ester (PC-88A) as extractant. The experiment was carried out on a laboratory scale by using a separating funnel to extract cobalt from the nickel sulfate solution with PC88A. The mixed solution was shake in separating funnel for a specified period of time, and after the solvent extraction experiment was finished the organic phase PC88 was separated from the nickel sulfate solution by decantation. The nickel and cobalt content in the aqueous nickel sulfate solution were then analyzed using Atomic absorption spectrophotometry (AAS). In this experiment, the variable for experiments were covering solution pH from 2 to 6, shaking time from 30 minutes to 120 minutes, shaking speed from 20 revolutions per minute (rpm) to 80 rpm, and the volumeratio of aqueous to organic phase (A:O ratio) was from 1:1 to 1:4. The effects that experimental variables to the cobalt extraction were observed in this experiment. The result of experiment at room temperature, solution pH 5, shaking speed 60 rpm, shaking time 90 minutes, A:O ratio 1:4 and concentration of PC- 88A 40% show 97.21% of cobalt can be extracted by PC-88A from nickel sulfate solution, thererfore it was necessary to conduct two stage extraction process to extract 100% of the cobalt from the nickel sulfate solution.

The utilization of nickel ore has increased along with the growing trend of electric vehicles. As a country with abundant nickel ore resources, Indonesia has received economic benefits from nickel ore export activities. However, since January 1, 2020, Indonesia has taken a policy to stop the export of nickel ore. Indonesia’s decision is interesting to study for two reasons. First, a ban on nickel ore exports has reduced state revenues. Second, the policy of stopping nickel ore exports creates a bad perception from partner countries that have depended on the supply of raw materials. This research aims to examine why Indonesia implemented the policy of stopping nickel ore exports in 2020. This research explores existing problems using a neomercantilism perspective through qualitative research methods with secondary data sources. The results show that stopping the export of nickel ore is Indonesia's neomercantilist policy to secure the supply of nickel ore and support domestic companies BUMN, to increase their relative position in international trade. It was concluded that stopping nickel ore exports in 2020 had improved Indonesia's relative position in international trade.

Nickel (Ni) is a ubiquitous metal with extensive industrial and nonindustrial applications. The increasing application of Ni has made it an unavoidable environmental pollutant; hence an increase in human overexposure and accumulation. Over-exposure to Ni results in hematotoxicity, immunotoxicity, genotoxicity, hepatotoxic, carcinogenicity and more notably, neurotoxicity. The neurological impact of Ni has garnered global concern and has made it subject to numerous investigations and published reports. Thus, this chapter discusses the neurologic impact of Ni overexposure such as behavioral, neurochemical and structural alterations, as well as addresses potential mechanism of Ni neurotoxicity. Additionally, the chapter highlights several potential therapeutic neuroprotective agents able to mitigate Ni-induced neurotoxicity.

Nickel (Ni) is a ubiquitous metal in the environment with increasing industrial application. While environmental and occupational exposure to Ni compounds has been known to result in toxicities to several organs, including the liver, kidney, lungs, skin and gonads, neurotoxic effects have not been extensively investigated. In this present study, we investigated specific neuronal susceptibility in a C. elegans model of acute Ni neurotoxicity. Wild-type worms and worms expressing green fluorescent protein (GFP) in either cholinergic, dopaminergic or GABAergic neurons were treated with NiCl2 for 1 h at the first larval (L1) stage. The median lethal dose (LD50) was calculated to be 5.88 mM in this paradigm. Morphology studies of GFP-expressing worms showed significantly increasing degeneration of cholinergic, dopaminergic and GABAergic neurons with increasing Ni concentration. Significant functional changes in locomotion and basal slowing response assays reflected that cholinergic and dopaminergic neuronal function, respectively, were impaired due to Ni treatment. Interestingly, a small but significant number of worms exhibited shrinker phenotype upon Ni exposure but no loopy head foraging behaviour was observed suggesting that function of D-type GABAergic neurons of C elegans may be specifically attenuated while the RME subset of GABAergic neurons are not. GFP expression due to induction of glutathione S-transferase 4 (gst-4), a target of Nrf2 homolog skn-1, was increased in a Pgst-4::GFP worm highlighting Ni-induced oxidative stress. RT-qPCR verified upregulation of this expression of gst-4 immediately after exposure. These data suggest that oxidative stress is associated with neuronal damage and altered behaviour due to developmental Ni exposure.

In this study, N-(((2-((2-aminoethyl)amino)ethyl)amino)methyl)-4-sulfamoylbenzamide was impregnated into the hydrous zirconium oxide matrix to yield N-(((2-((2-aminoethyl)amino)ethyl)amino)methyl)-4-sulfamoylbenzamide/hydrous zirconium oxide composite (AESB/HZO). The composite material was used to remove Ni(II) from aqueous environment. AESB/HZO was characterized using Fourier transform infrared, scanning electron microscopy with energy dispersive X-ray, and thermogravimetry-differential thermal analyses. An experimental design approach was utilized to model and optimize the variables of adsorption of Ni(II) onto the AESB/HZO composite. Four experimental parameters were selected as independent variables: contact time, pH, adsorbent dose, and initial Ni(II) concentration. A multivariable experimental design was used to establish quadratic model to describe the relationship between percent removal of Ni(II) and four independent variables. At the optimum conditions (contact time: 85 min, pH: 6, adsorbent dose: 10 mg/20 mL, and initial Ni(II) concentration: 20 mg L ⁻¹ ), high removal efficiency (99.35%) was achieved, which is reasonably well predicted by the quadratic model. The sorption of Ni(II) is dependent on pH and ionic strength at pH < 6.0. At low pH, -NH and -NH 2 groups are protonated, whereas the -SO 2 - group is available for binding with Ni(II) and the sorption of Ni(II) is mainly governed by outer sphere surface complexation. In the pH range 6.0-7.5, -NH, -NH 2 , and -SO 2 - groups are available for binding with Ni(II) and the sorption is mainly governed by inner-sphere surface complexation. Adsorption isotherm data fitted well to the Langmuir model and the maximum adsorption capacity was found to be 96.03 mg g ⁻¹ at 303 K. The results of present investigation demonstrated that AESB/HZO has a good potential for Ni(II) removal from aqueous solution.
Gastrointestinal cancers describe malignant changes that affect the organs of the digestive system and its ancillary organs and are responsible for more cancers and cancer-related deaths than any other system in the body. Nickel is widely used in various industries, causing many human cancers through different mechanisms. Our present study is designed to estimate nickel concentrations in serum samples from patients with different types of gastrointestinal cancers. The study was carried out in 45 patients with many types of gastrointestinal cancers at Al-Biruni University Hospital for Cancerous Diseases in Syria compared with 35 healthy controls. All measurements of serum were done with a graphite atomic absorption spectrophotometer equipped with a deuterium lamp. Our results showed that patients with gastrointestinal cancers had significantly higher serum levels of Ni than healthy controls (p < 0.0001), and there were no statistically significant differences between the four types of gastrointestinal cancers included in the study (p > 0.05). The increase in serum nickel concentrations has a direct effect on the incidence of gastrointestinal cancers by influencing the mechanisms that induce cancer by nickel.
Prostate cancer is one of the most common cancers among workers of various industries that depend on nickel extensively, through different mechanisms. Our present study is designed to estimate nickel concentrations in serum samples from patients with prostate cancer compared to the control group of healthy subjects. The study was carried out on 43 patients with prostate cancer at Al-Biruni University Hospital for Cancerous Diseases in Syria compared with 35 healthy controls. All measurements of serum were done with a graphite atomic absorption spectrophotometer equipped with a deuterium lamp. Our results showed that patients with prostate cancer had significantly higher serum levels of Ni than healthy controls (p < 0.0001). These findings suggest that increased nickel serum levels are associated with an increased risk of prostate cancer in industrial workers through one of the carcinogenic mechanisms.
