偏最小二乘-分光光度法同时测定钢样中铬、锰
Simultaneous Spectrophotometric Determination of Chromium and Manganese in Steel with the Algorithm of Partial Least Square
摘 要
在硫-磷混合酸介质中,钢铁样品中铬和锰在银离子存在下用过硫酸铵溶液分别氧化至六价和七价,用分光光度法同时测定样品中铬和锰的含量.在380~600 nm波长范围,每间隔10 nm测定一次吸光度.借计算机及Matlab语言编写程序,对所得吸光度数据用偏最小二乘计算法处理并获得结果.

Abstract
Chromium(Ⅲ) and manganese(Ⅱ) in H2SO4-H3PO4 mixed acid solution of steel sample were oxidized to Cr(Ⅵ) and Mn(Ⅶ) by (NH4)2S2O8 solution in the presence of Ag+-ion.Contents of Cr and Mn in sample were determined simultaneously by spectrophotometry through taking values of absorbance at wavelength intervals of 10 nm in the range from 380 to 600 nm.The data obtained were treated by the algorithm of partial least square,with the help of a computer programmed with Matlab language.
