摘要:
砷对环境和人类健康都十分有害，是海洋环境监测的重要指标。由于砷的形态与其毒性、迁移及生物利用有效性紧密相关，因此海水中的砷形态分析受到了国内外广大学者的关注，砷形态的分析方法也不断得到更新和发展。对近20年来海水中砷形态分析的研究成果进行综述，主要介绍了分离与富集技术、检测技术及多种联用技术的基本特点和实际应用，并对海水中砷形态分析的未来发展进行了展望。基于消耗试剂少、富集倍数高等特点，固相萃取（SPE）和梯度扩散薄膜（DGT）技术成为近年来砷形态研究的重要分离富集技术。吸附剂和结合相分别是影响SPE和DGT分离富集的关键，很多学者相继开发了不同的吸附剂和结合相，并将其与原子吸收、原子荧光、电感耦合等离子体质谱等检测技术联用进行海水中砷形态的测定研究，这些联用方法是目前金属形态分析中有效的新方法。
Abstract:
As an important indicator of marine environmental monitoring, arsenic is very harmful to the environment and human health. Because the forms of arsenic are closely related to their toxicity, migration and bioavailability, the speciation analysis of arsenic in seawater has attracted the attention of researchers in China and abroad, leading to continuous update and development of the analysis method. In this paper, the research results of speciation analysis of arsenic in seawater in the past two decades are reviewed. The basic characteristics and practical application of arsenic separation and enrichment technologies, detection technologies, and a variety of combined technologies were mainly introduced, and the future development of arsenic speciation analysis in seawater were prospected. Based on the characteristics of less reagents consumption and higher enrichment times, solid phase extraction (SPE) and diffusive gradients in thin films(DGT) have become the most important separation and enrichment technologies for arsenic speciation research in recent years. Adsorbent and binding phase are the key factors affecting the pretreatment effects of SPE and DGT, respectively. Therefore, many scholars have developed a variety of adsorbents as well as the binding phases. Advanced analysis technologies such as atomic absorption spectrometry, atomic fluorescence spectrometry, inductively coupled plasma mass spectrometry and other detection technologies were integrated with adsorbents and binding phases to determine the arsenic speciation in seawater. These combined methods are effective and innovative strategies in metal speciation analysis.
