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.
