目前,国内外对砷的溶出伏安法测定作了许多工作,但是测定生物材料中的砷必需经过有机质的消化,以往多用酸式消化法,这个过程既麻烦又费时,因此这个问题值得进一步探讨。另一方面对样品中把砷分离和还原问题是测砷的关键,往往不容易达到理想,这就直接影响测定结果的准确性。为此,本文拟着 At present, many studies have been done on the determination of arsenic by voltammetry at home and abroad, but the determination of arsenic in biological materials must be digested by organic matter. In the past, acid digestion was often used. This process is cumbersome and time-consuming, so this problem deserves further study . On the other hand, the key to arsenic determination and separation of arsenic in samples is often not easy to reach the ideal, which directly affects the accuracy of the determination results. To this end, this article is intended
