环境中痕量有机锡的前处理及检测方法研究综述

Progress in Research on Pretreatment Method for Organotin in Environment

有机锡的痕量与超痕量分析技术是当今环境安全分析领域的前沿技术,由于有机锡的种类繁多,理化性质存在差别,所以在提取、衍生和测定中均存在较大的困难。选择合适的前处理方法和检测方法对环境中复杂背景下的超痕量有机锡分析具有重要意义。近年来有机锡的前处理方法和检测技术都取得了较大进展,其中固相微萃取(SPME)等技术得到了广泛的应用。本文综述了国内外有机锡测定的主流前处理方法、检测方法及进展,在此基础上,对最新的有机锡形态前处理技术发展趋势和检测方法进行展望。

In the field of today＇s environment security analysis,trace organotin and ultra-trace analysis technology is a cutting-edge technology,due to the variety of alkyltin,and there are differences in the physical and chemical properties,resulting in difficulties in the extraction,derivation and determination.Therefore,it is of much importance to select appropriate pre-treatment and testing methods in the ultra-trace organotin analysis in the environment of the complex context.Recent years has witnessed great progress in the organotin pre-treatment and testing methods,particularly in the solid-phase micro-extraction（SPME） technology.The paper overviews the research at home and abroad on the mainstream pre-treatment and testing methods for the determination of organotin,on the basis of which,discusses the latest developmental trend in this light.
