Ekstraction of noble metals by using Cyanex 302
Cyanex 302 was used for removal of noble metal ions from their nitrate and hydrochloricnitrate solns. Extn. factors and isotherms of the extn. of Pt(IV), Pd(II), Au(III) were detd. by at. absorption spectroscopy. Extn. efficiency of noble metal ions increased in series: Pt(IV) < Pd(II)) < Au(III).
