| Abstract: | Suspension copolymerization of 1-vinyl-1,2,4-triazole with acrylonitrile was used to synthesize an insoluble heat-resistant copolymer possessing sorption activity. An effect of the nature and concentration of acids on the recovery of noble metal ions Pt(IV), Pd(II), Au(III), and Ag(I) was observed. The kinetic and sorption characteristics of the copolymer were evaluated and the possibility of its application was assessed. IR and Raman spectroscopies were used to elucidate the mechanism of interaction of the copolymer with noble metal ions. |
