Synthesis and Application of Solid-phase Reagents with Formzane Groups in Environmental Analysis

固定化有机光敏感现代水质分析方法,已经引起了人们的关注.用于固相光谱比色分析检测技术,确定待检测污染物中有机与无机元素的排列、相互作用以及最佳结合方式,是建立固定化有机光敏分析检测系统的关键.杂芳基甲簪是一种无机与有机基质的表面改性剂,也是发色基团多配位复合试剂.其官能团与待检测污染物及有机试剂相互作用的原因是取代基甲簪分子的引入,使重金属污染物检测的选择性、对比度和显色速度增强,且金属离子络合稳定.本文对甲簪基团、固相有机光敏感试剂合成的几种方法进行综述,对固相试剂与甲簪基团的作用和实际应用进行了探讨.

The optical sensor elements on the base of immobilized organic reagents was paid special attention to synthesis in modern water analysis,and the solid-phase spectroscopy techniques were developed for determining elements and visual testing.Determining optimal combination of an organic element,matrix and interaction with an analyte is the major problem when constructing analyte detection systems.Hetaryl formazanes are surface modifiers of inorganic and organic matrixes due to the presence definite functional groups which are responsible for interaction between an organic reagent and analyte,formazanes are general chromophoric polydentate complex-forming reagents.The introduction of substituents（chemical-analytical groups） into the formazane molecule allows to manage chemical-analytical characteristics of the reagents enhancing selectivity,contrast,velocity and stability of analytical effect when complexing with metal ions.The approaches of synthesis of solid-phased reagents with formazane groups were reviewed,and the results of their properties and practical applications of solid-phased reagents with formazane groups were generalized.
