Abstract

Solvent extraction of silver ions using tetrakis(N,N-diethylaminocarbonylmethoxy)-p-t-octylcalix[4]arene (EATOC) in chloroform from nitrate medium is presented. The influences on the extraction conditions affecting the behaviour of extraction depending upon the  factors such as concentrations of acids, extractants and silver ions as well as extraction time were investigated. Various stripping  reagents for back extraction to recover the loaded silver ions by forward extraction process were applied. The extraction mechanism of silver ions using EATOC was established on the 1H NMR chemical shift of the extractant as well as the slope assessments of extraction  conditions both before and after loading the silver ions.
