Abstract
The sorption properties of nitrogen-containing polyacrylonitrile-based fibrous sorbent modified with thiosemicarbazide (Glipan-1) to platinu m(IV) chloride complex (K2PtCl6) were studied. The effect of temperatu re and concentration of chloride and hydrogen ions on sorption was ana lyzed. The kinetic and capacity characteristics of this sorbent were d etermined in hydrogen chloride and chloride solutions. The composition of compounds formed in the fiber and the probable mechanism of platin um(IV) chloride complex sorption were evaluated.
