基于Biharmonic样条的曲面插值模型对脱色率随脱色时间、PANI-ZnO/α-Fe_2O_3复合材料投入量变化关系进行曲面拟合,获得误差平方和(sse)为1.688e-25,变量间相关程度系数(R-square)为1。利用杂草算法对降解条件进行全局寻优,经过200次迭代,杂草算法耗时484.199320 s输出了寻找到的最优解:脱色率为98.1972%,催化反应时间为464.2652 min,PANI-ZnO/α-Fe_2O_3复合材料投入量为41.1397 mg。首次实现了杂草算法应用于多变量的复杂化学问题求解,计算结果表明杂草算法可以快速收敛,方法准确可靠。
Based on the Biharmonic spline interpolation model, the decoloration rate was fitted to the surface of PANI-ZnO / α-Fe_2O_3 composites by surface fitting. The square error (sse) was 1.688e-25. The correlations among the variables The coefficient (R-square) is 1. After 200 iterations, the weed algorithm took 484.199320 s to output the optimal solution. The decolorization rate was 98.1972% and the catalytic reaction time was 464.2652 min. The PANI-ZnO / α-Fe_2O_3 composite material input amount of 41.1397 mg. For the first time, the weed algorithm is applied to solve complex chemical problems with multivariable results. The calculation results show that the weed algorithm can converge quickly and the method is accurate and reliable.
