Sorption of Pt(IV) Chloride Complexes with a Chelating Resin Based on Modified Lignin

摘要

Sorption of hexachloroplatinic(IV) acid on a new phytosorbent based on lignin modified with thioamide groups was studied.The sorption capacity of the sorbent for Pt(IV) was examined in relation to the Pt(IV) concentration in the aqueous phase,pH,temperature,and sorption time.The kinetic characteristics of sorption of Pt(IV) on the lignin sorbent were studied.
