Abstract
Arsenic (III) and arsenic (V) in disused mine tailing samples have been determined simutaneuously by hydride generation inductively coupled plasma atomic emission spectrometry (HG-ICP-AES). Total arsenic was determined using 2% <TEX>$NaBH_4$</TEX> and 6 M HCl after prereduction of As(V) to As(III) with) 1M KI. Arsenic (III) was determined selectively using citrate/citric acid buffer with range of pH 5-6, it was determined by HG-ICP-AES. Arsenic (V) can be evaluated by the differences. According to the results, arsenic (V) was over 90% among the total arsenic extracted from disused mine tailing samples.
