EXTRACTION OF SILVER BY 7402-LEVEXTREL RESIN
Abstract:
The distribution coefficient of silver in extraction with CL-7402 levextrel in thiosulfate medium was investigated. The adsorption capacity of resin for Ag+ ion was found to be 0,29mmol/g resin, and the complex ratio of resin to Ag(S2O3)23- was 3:1. The nechanism of the adsorption is discussed in terms of IR spectra.
