中文摘要：

砷是一种类金属元素，砷及其化合物具有极强的毒性和致癌性。该文综述了水中砷及其化学形态分析方法的研究进展，对光度法、原子吸收光谱法、原子荧光光谱法、电化学法、电感耦合等离子体质谱法以及联用技术在水砷测定中的应用现状进行介绍，提出HPLC—ICP—MS联用技术是今后分析方法的发展方向。

英文摘要：

As metalloid, arsenic and arsenic compounds present high toxicity and carcinogenicity. Progress on analysis of arsenic and its chemical speeiation in water was reviewed in this paper, the application of spectrophotometry, atomic absorption spectrometry , atomic fluorescence spectrometry, electrochemical technique, ICP-MS and combination were introduced ,and the application of HPLC-ICP-MS was considered as the best way.
