The presence of trace metals in polluted mine water remains a concern due to its adverse effects on human health. This paper evaluates a PVC-D2EHPA based PIM containing silver nanoparticles as a tool to extract and measure trace metals in polluted water. Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), contact angle a...

The shortcomings of conventional sampling methods as grab sampling has led to the development of alternative approaches especially those based on passive samplers. The challenge of passive sampler’s despite being cheap to use and being integrative in nature is that there are limited commercial suppliers especially for those on water related applica...

Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as stan...

The poly(pyrazol-1-ylmethyl)benzenes L1-L5 react with [PdCl 2 (NCMe) 2 ] or [PdClMe(COD)] to form dinuclear palladium complexes [{PdClX(3,5-Me 2 pzCH 2) 2-1,2-C 6 H 4 } 2 ] (X = Cl (1), Me (2)), [{PdCl 2 (3,5-Me 2 pzCH 2) 2-1,3-C 6 H 4 } 2 ] (3), palladium complexes [{Pd 2 (µ-Cl) 2 Me 2 (3,5-Me 2 pzCH 2) 2-1,3-C 6 H 4 }] (4), [{Pd 2 (µ-Cl) 2 X 2 (3...
