阳极溶出伏安法(Anodic StrippingVoltammetry简称ASV),是近几年来发展迅速的一种新的测定痕量元素的电化学分析技术,由于仪器简单,价格低廉,再加具有灵敏度高、取样量少、可同时测定数种元素等优点,得到了愈来愈广泛的应用。1970年Matson首先采用ASV法测定血铅,而在生物样品中测定锌、铜、镉、砷、铋、铊等元素也有大量报道。本文仅就ASV在测定血铅方面的原理、样品的消化、影响测定的因素及微量血样的采集和贮存等作一扼要综述。
Anodic Stripping Voltammetry (ASV) is a new electrochemical technique for the determination of trace elements, which has been developed rapidly in recent years. Due to its simple instrument, low cost, high sensitivity and small sample volume, Can simultaneously determine the advantages of several elements, has been more and more widely used. In 1970, Matson first used the ASV method to determine blood lead, while in biological samples, there were also many reports on the determination of zinc, copper, cadmium, arsenic, bismuth and thallium. This article reviews only the principle of ASV in the determination of blood lead, the digestion of samples, the factors affecting the determination and the collection and storage of trace blood samples.
