摘要
用紫外可见光谱法研究了在碱性溶液中[Ni(PnAO)-H]^++H_2O_2→[Ni(PnAO)-6H]~0的反应动力学并提出了包含自由基·OH的复杂反应机理。采用经典确定反应机理的方法及Gauss-Newton-Marquardt非线性拟合和Runge-Kutta解一次微分方程组程序处理数据并获得了良好的结果。改变碱浓度及双氧水浓度所得结果支持所拟机理。
The reaction of [Ni(PnAO)-H]+ + H2O2→[Ni(PnAO)-6H]0 was studied in a basic solution with UV-Vis spectra and a complicated mechanism which included the free radical ?OH was suggested. The classical method for determining reaction mechanism was used and Gaus-Newton-Marquardt nonlinear fitting program and Runge-Kutta program for solving the first order differential equations were used for treating the data and a good result was obtained. The effect of the concentration of base and H2O2 also were discussed and the result supports the mechanism.
