Silica modified with zirconium oxide for on-line determination of inorganic arsenic using a hydride generation-atomic absorption system.

Abstract

In the present work, an on-line pre-concentration system, using SiO(2)/ZrO(2) as solid phase adsorbent, for the determination of low concentrations of arsenic was developed. In this procedure, total inorganic arsenic present in the sample is reduced to As (III) with l-cysteine and the solution is passed into a glass column (varphi(i)=3mm; h=35mm) containing… (More)
