摘要：
Waste batteries contain toxic metals (Pb, Ni, Zn, Fe, etc.) in high concentrations. In order to prevent harmful effects on human health and environment, it is necessary to recycle them. In this paper, prospective applications of aqueous two-phase systems for isolating and separating the components of leach liquors of batteries have been considered. The extraction of metal cations in the systems based on poly(ethylene oxide) with molecular masses of 1500 and ammonium sulfate depending on the process conditions has been studied. A flow diagram of the separation of the components of leach liquors that uses a studied aqueous two-phase system in the presence of KSCN complexing agent has been suggested.
