双安培法是一种灵敏度很高的分析方法,近年来已有许多应用.作者曾将双安培示波法用于确定氧化还原滴定的终点.本文将双安培示波技术用于催化动力学分析获得成功.在动力学分析中,加入不同浓度的催化剂,用本法测出指示组分达到一定浓度的时间,即可测得催化剂的浓度.因为示波器很稳定,测定电流的灵敏度很高,且不受试液的颜色或沉淀的影响,所得结果的重现性好,线性范围较宽,所以此法比光度法优越. Double amperometry is a highly sensitive analytical method and has been used in many applications in recent years. The authors have used dual ampere oscillometry to determine the end point of redox titration. In this paper, dual amps were used in catalytic kinetic analysis In kinetic analysis, adding different concentrations of catalyst, using this method to measure the concentration of the indicator component reaches a certain time, you can measure the concentration of the catalyst because the oscilloscope is very stable, the determination of the current sensitivity is high, and Not the color of the test solution or precipitation, the results obtained good reproducibility, a wide linear range, so this method is superior to photometry.
