Studied the sorption Pb2+ by sorbents based on crown ether (4,4',(5')-di(tert-butyl)dicyclohexyl-18- crown-6) and phosphoryl podand (1,8-bis[2-(diphenylphosphorylmethyl)phenoxy]-3,6-dioxaoctane). A high degree of recovery of Pb2+ by sorbent based phosphoryl podand from weakly acidic solutions, as well as salt acid solutions by sorbents based on crown ether. For sorbents based on crown ether it shows that the highest degree of extraction is achieved by using as a support hydrophobizated silica gel.
