“…Jarosite is produced as a byproduct during the metallurgical extraction and purification of the zinc ore. Debari zinc smelter plant (Udaipur, India) is one of the biggest plant which has an yearly manufacturing capacity of 92, 000 MT of high zinc metal via electrolytic extraction process. [1][2][3] During this process, huge quantity of solid waste or residue namely 'ammonium Jarosite' is released, which is environmentally hazardous because of the presence of toxic heavy metals like lead, cadmium, copper, arsenic, aluminum., [4][5][6] and its disposal has become a major concern. Some elements are considered as highly noxious [7][8][9] and these are categorized as deadly chemical.…”

Jarosite is an essential solid industrial waste material which is generated during the hydrometallurgical processing of zinc in smelters. Besides zinc and iron, Jarosite also contains toxic heavy metals like Pb, Cd, Al, Cr, Cu etc. due to which it is environmentally hazardous. Due to the presence of heavy metals, the useful Zn, Fe components cannot be utilized safely. Therefore, it is necessary to remove Pb(II), a major toxic element, to make it useful. In this report, a green process for immobilization of Pb(II) using phosphate materials (physiochemical adsorption) is discussed. Jarosite was used as a precursor for synthesis of the ZnÀ Fe binary nano-composite.Mitigation of Pb(II) by this process was assessed by the batch experiments, which showed significant reduction in leaching of Pb(II). The mechanism of Pb(II) immobilization involve the dissolution of phosphate materials (KH 2 PO 4 , NH 4 H 2 PO 4 and CaH 2 PO 4 ) to a lower pH � 3 followed by precipitation of Pb(II) in the form of pyromorphite complex. The results indicated that the concentration of Pb(II) was reduced by 90-95 % which was pH dependent with a high uptake (325 ppm) of lead ion in the pH range of 5.5-6.0. This physicochemical process brings new perspectives for reuse of a polluting solid industrial waste.
