Abstract:

Effect of the acidity of the sorption solution on the recovery of Cu(II), Ni(II), Co(II), Ag(I), and Pd(II) ions was studied for dithiooxamidated polysiloxanes with degrees of modification of 0.10 and 0.21. The constant acidity of the solution was maintained with ammonia, acetate, and ammonia-acetate buffer solutions. The optimal sorption conditions of metal ions from individual solutions were found. The distribution coefficients and pairwise selectivity coefficients were calculated for all the ions studied. It was fund on the basis of the selectivity coefficients that introduction of dithiooxamide groups into the structure of polysiloxane yields an effective sorbent for recovery of Pd(II) and Ag(I).
