In this work, the separation potential of a new "magmolecular" process for ions of antimony(III) from wastewater was studied. The magmolecular process is a technique in which a high gradient magnetic field is applied to eliminate heavy metal from wastewater. In this process, specifically we have synthesized two nanoadsorbent …

The electrochemical separation process was performed in molten NaCl-CaCl2. The content of Sb (atomic percent) in the Pb-Sb alloy was reduced from 1% to less than 0.01% (atomic ratio). The recovery principle lies in the different alloying potentials between Ca-Sb and Ca-Pb. Hence, molten salt electrolysis is a promising separation …

Antimony is a dissolved state in water that has a strong migration ability, and when antimony is adsorbed to particles or sediments in water, its migration ability will be reduced. The reduction process can release antimony from sediments into the water environment. The transformation process of antimony is Sb(III) → Sb(V) → Sb(OH) 6 − ...
