Copper and cobalt from industrial operations build up in the environment, posing a
substantial health risk. This study examined how ethylenediaminetetraacetic acid (EDTA) …

Heavy metals such as zinc and nickel can be found in wastewater from steel electroplating
trace concentrations. These heavy metals harm the ecosystem and human health, which …

Nickel (Ni) is a ferromagnetic and corrosion-resistant metal, whose demand has risen
remarkably in recent years. Depletion of its sulphide and laterite ores has necessitated the …

Removal of iron and aluminum from nickel-bearing pregnant leach solution is imperative
prior to recovering nickel. However, the mechanisms into the loss of both nickel and cobalt in …
