Силікагель з іммобілізованим полііоненом у визначенні аніонних комплексів Au(III)

Abstract

Onium polymerization has been executed in a silica surface layer for the first time. Adsorption properties of silicas with adsorbed and in situ immobilized polyionene towards [AuCl4] − are studied using atomic absorption and X-ray fluorescence analyses. A method of quantitative sorption-X-ray fluorescence determination of Au(III) anionic form has been developed. The state of gold on the adsorbent surface is investigated by difuse reflectance spectroscopy.
