摘要
用覆盖SnO2/Sb2O3活性层的钛作阳极，对染料茜素红水溶液进行电降解，测定了不同pH值下、不同电解时间的紫外可见吸收光谱，并用主成分分析、潜变量投影、遗传算法以及渐进因子分析等化学计量学方法解析得到中间型体的动力学曲线和纯光谱，最后对茜素红水溶液电降解的机理做了初步探索。
The ultraviolet (UV) absorption spectra of alizarine red Sarmples obtained from its electrolytic solution every definite minute were acquired under different pH value conditions. Using a variety of chemometrics methods such as principal component analysis, heuristic evolving latent projections, geneic algorithm and evolving factor analysis, the dynamic curve and the UV spectrum of pure substance (alizarine red and intermediate) were calculated out. Finally the essay makes a preliminary study on the electrolytic mechanism of alizarine red, and resolves the test and verification of the intermediate during the electrolysis process.
