化学振荡在分析化学中的应用综述

Critical review:application of oscillating chemical reaction in analytical chemistry

对近十多年(2000—2014年)化学振荡现象在分析化学中的应用进行全面评述.主要综述了Belousov-Zhabotinsky(B-Z)振荡体系、铜催化振荡体系(如Cu(II)-H2O2-KSCN)和Briggs-Rauscher(B-R)振荡体系在分析中的应用,被测物包含了金属离子、阴离子、气体和各种有机物等.化学振荡分析技术具有检测费用低廉、操作简便、仪器简单、较宽的线性检测范围和较低的检测限等优点,是一种检测物质的新方法.

Oscillating chemical reaction ,a vivid example of nonlinear equilibrium ,supplied us with new analytical method by using analyte perturbation technology .This review covers recent development in utilization of oscillating chemical reaction in analytical chemistry in fourteen yeas . The methods being evaluated focus on the exterminating the metal ions , anions ,gas or various organic compounds by using Belousov-Zhabotinsky （B-Z） oscillation system ,copper-catalyzed oscillation system and Briggs-Rauscher （B-R） oscillation system . The methods have many advantages ,such as low cost ,easy operation ,simple apparatus , wide linear determination range and lower determination limit .
