摘要
以高效液相色谱和毛细管电泳相结合的手段研究了pH=9.24时双氧水-硫氰酸盐氧化体系的动力学行为。通过两种分析方法,反应体系中各物种均能得到较好的分离,检测得到碱性条件中氧化产物为硫酸根和氰酸根。使用初始速率法进行数据处理,获得硫氰酸盐和双氧水均显示为一级动力学。
The oxidation kinetics of the hydrogen peroxide-thiocyanate at pH = 9. 24 was studied by high performance liquid chromatography and capillary electrophoresis simultaneously. Several compounds could be separated well with these two analysis methods and the result showed sulfate and cyanate were the oxidation products under weak alkaline solution. The experimental data processed by initial rate method suggested that the rate law was the first order with respect to hydrogen peroxide and thiocyanate.
