摘要
研究了在４，５－二溴苯基荧光酮（ＤＢＰＦ）－ＣＴＭＡＢ－ＯＰ显色体系中，用偏最小二乘法对痕量Ｗ、Ｍｏ、Ｚｒ进行同时分光光度测定．结果表明，它不仅保持了ＤＢＰＦ的高灵敏度，而且克服了三组份间的干扰，其测定的相对误差小于９％．
The principle of partial least squares method (PLS) is described, Which is applied to the simultaneous spectrophotometric determination of the mixed samples of W(Ⅵ), Mo(Ⅳ) and Zr(Ⅳ) in the 4,5-dibromophenylfluorone-CTMAB-OP system. The results are satisfactory and the relative errors are less than 9%. Compared with linear programming method(LP), PLS is foster more accurate and reliable, applicable especially to processing samples in batches.
