采用Gl算法改进了快扫伏安曲线的数值模拟,提高了模拟计算的速度.使用单纯形优化-数值模拟方法,以电流、峰电位误差的加权值作为拟合参数的评价函数,对二茂铁在0,3mm直径铂盘电极上,不同扫速下的循环伏安图进行了拟合.在拟合过程中自动进行伏安图基线的校正,同时拟合出标准非均相速度常数k~0,未补偿溶液电阻R_u以及双电层电容C_(dl)等重要的参数值,所得k~0值与文献报道结果一致. Gl method was used to improve the numerical simulation of fast sweep voltammetry curve and improve the speed of simulation calculation.Using the method of simplex optimization and numerical simulation and the weighted value of current and peak potential error as the evaluation function of fitting parameters, The cyclic voltammograms of iron at 0,3 mm diameter platinum disk electrode at different sweep speeds were fitted, and the baseline of voltammogram was automatically corrected during the fitting process, and the standard heterogeneous velocity constants k ~ 0, uncompensated solution resistance R_u and electric double layer capacitor C_ (dl) and other important parameter values, the resulting k ~ 0 values ​​consistent with the reported results.
