摘要
微量污染物的测定是环境临测的重要内容,分光光度法是测定微量污染物广泛应用的主要方法。为了提高分光光度法的灵敏度和选择性,研究新的显色体系是重要的途径。本文以生成三元络合物新体系作为研究的重点,论述了三元络合物的基本概念、类型与组成及其主要特性;阐明三元络合物在环境监测萃取分光光度法、水相分光光度法及胶束增溶分光光度法中应用的优越性。同时,简要介绍了三元络合物在环境监测中广阔的应用前景和研究方向。
Spectrophotometry is the main means widely used in determing the trace pollutants to improve the sensitivity and selectivity of spectrophotometry. The generation of new ternary complex system is taken as its impor-tance in this paper. The fundamental concept, type, composition and main special features of ternary complex are discussed and the advantages of the ternary complex used in environmental monitoring are described.Mainwhile, the research direction and the promising future of ternary complex in envi-ron mental monitoring are also mentioned briefly.
