The increase of global environmental restrictions concerning solid and liquid industrial waste, in addition to the problem of climate change, which leads to a shortage of clean water resources, has raised interest in developing alternative and eco-friendly technologies for recycling and reducing the amount of these wastes. This study aims to utiliz...
Boiler ash, produced by burning heavy fuel oil (HFO) in electrical power plants, is one of the most serious environmental problems facing oil-rich countries. However, boiler ash also contains some important industrial elements like V, Ni, Zn, etc., and has great potential for positive utilization. The present work aims to maximize the possible util...

The water leaching solid residues (WLSR) obtained from salt-roasting Egyptian boiler ash are considered an essential secondary resource for (13%) nickel and (5.6%) zinc extraction. Hence, the current study aims for the cost-effective and high purity Ni, Zn, Fe and Mg metal ion extraction from (WLSR) using a sulfuric acid leaching process. The facto...

... The initial concentration of metal ions can also affect the adsorption capacity. Generally speaking, as the concentration of ions in the solution increases, the adsorption capacity will rise and then stabilize, because the high concentration of ions will provide a greater adsorption driving force and dimer structures might be formed, and then the maximum adsorption capacity will be reached after the adsorption site is fully saturated [82,85]. For example, Ibrahim [82] et al. studied the effect of heavy metal ions at different concentrations of 10-80 mg/L on the adsorption efficiency of zeolite. ...

... The accompanying heavy metals in fuels, such as V, Fe, and Ni, will accumulate in a solid waste known as fly ash, after combustion. V and Ni are valuable metals with several industrial and commercial uses (Chen et al. 2021;Bakkar et al. 2023;Ibrahim et al. 2023;Lim et al. 2023) and both are among the most hazardous components of OBFA (Bakkar et al. 2023). Large quantities of OBFAs are produced by oil-rich nations, and future projections indicate that this trend will accelerate in response to increased energy demand (Basha Responsible Editor: Ioannis A. Katsoyiannis et al. 2020;Bakkar et al. 2023;Hamidi et al. 2023b) and gas supply deficiencies. ...
