摘要
随着我国针对饮用水、食品等砷质量浓度制定了强制性标准,准确、快捷、有效地测定砷的质量浓度,成为近年来分析方法研究的重要内容.从分离、富集、进样方式与光度法测定相结合等方面对近年来国内外痕量砷的分析技术进行了综述,认为目前的分析方法主要有荧光法、电感耦合等离子质谱法和发射光谱法、氢化物发生原子吸收法光谱法以及联用技术等,其中最重要的痕量光分析法为氢化物发生原子吸收法.
with some compulsory standards have been set to the trace of arsenic in drinking water, food etc in china. The accurately, simply and efficiently of measuring arsenic becomes more important in the analytical researches in recent years. The paper gives a review of the new progress in analytical methods of trace arsenic broad and abroad which mainly focus on the methods of preprocessing, such as separation, enrichment and forms of materials measured. Inductively coupled plasma mass spectrometry （ICP-MS）, inductively coupled plasma atomic emission spectrometry （ICP-AES）, hydride generation atomic absorption spectrometry （HG-AAS） are used more frequently. Among them the most principal measurement is HG-AAS.
