Abstract:

Sorption of palladium(II) from model solutions with polysiloxanes modified with amine and thiourea groups was stidied and it was found that the maximum sorption on aminopropyl polysiloxane is shifted slightly to alkaline region compared with a sulfur-containing sorbent. First time an effect of a series of external factors on a sorption kinetics of palladium with polysiloxanes was researched, diffusion coefficients of sorbate ions were calculated, and evaluation of their dependence on an initial concentration of metal, a grain diameter of the sorbent, and a temperature of sorption environment was carried out. It is shown that quantitative desorption of palladium from thiocarbamoylated polysiloxane is achieved by double treating the sorbent with hydrochloric acid solution of thiourea at high temperature.
