- Аннотация: The sorption of lead by an impregnated type sorbent based on the phosphorylpodand, 1,8-bis[2-(diphenylphosphorylmethyl)phenoxy]-3,6-dioxaoctane, was studied. Sorption isotherms were plotted, as well as the data on kinetics, selectivity, and dynamics of sorption were obtained. The phosphorylpodand-based sorbent attains the sorption equilibrium of lead extraction with a high rate. The maximum sorbent capacity was achieved when the equilibrium concentration of lead in solutions was more than 150 mg L−1. The 1,8-bis[2-(diphenyl-phosphorylmethyl)phenoxy]-3,6-dioxaoctane-based sorbent shows a high selectivity for lead sorption from neutral solutions. The output curve of lead sorption was plotted. The dynamic exchange capacity and total dynamic capacity of the obtained sorbent were determined.
