摘要
The aim of this study was to develop a method of Se and As determination in drinking water by electrochemical hydride generation coupled with AAS. Three types of electrolytic cells were constructed and optimized for the determination. Two cells (thin-layer and tubular) were finally chosen for their low inner volume and a high hydride generation efficiency (ca. 90 %). The limits of detection of As(III) and Se(IV) were 0.07 and 0.37 ng ml(-1), respectively. The accuracy of the method was verified using reference materials.
