岭回归法测定钝化液中三组分含量的研究

Simultaneous Determining Concentration of Three Components in Passivating Solution by Ridge Regression Spectrophotometry

将岭回归分光光度法(LHG)应用于电镀锌的钝化液中的铬酐、硝酸、高锰酸钾等三组分浓度的同时测定 试验结果表明,该法对样品各组分的平均回收率在94%～105%之间,样品不经分离,不需加任何试剂即可测定

Three main components CrO_3, HNO_3,KMnO_4 etc in passivating solution are determined simultancously by the ridge regression UV-absorptiophotometry. The experimental results show that the average recovery of each component is all in the rang from 94% to 105%. The analysis can be carried out easily and rapidly without any separation, and satisfactory results are obtained.
