中文摘要：
砷是自然界中广泛存在的一种有毒类金属，砷过量会危害人类的健康甚至致癌。选择适当、简便、可靠的测定方法是现代痕量分析技术取得重大发展的必要条件。该文综述了近年来痕量砷的测定方法，主要包括砷斑法、分光光度法、催化极谱法、原子吸收法、电感偶合等离子体质谱法等，并展望了联用技术在砷形态的分离和测定的应用前景。
英文摘要：
Arsenic is a toxic metal existed in nature widely. Arsenic excessive wilt endanger human health or even cause cancer. Selecting proper, simple, reliable method for the determination is an essential condition of modem trace analysis technology achieving significant development. The determination of trace arsenic in recent years are re- viewed, including arsenic stain method, spectrophotometry, catalytic polarographic method, atomic absorption spec- trometry, inductively coupled plasma mass spectrometry, and the application prospect of hyphenated techniques in the separation and determination of arsenic speciation is prospected in this paper.
