摘要：

A partial least squares (PLS) regression has been used to carry out the simultaneous determination of Pb(II), Sn(IV) and Cd(II) by differential pulse polarography (DPP) because overlapping peaks exist. But this multivariate regression requires the measurement of a large number of calibration samples, so a standardization procedure, the piecewise direct standardization (PDS) method, has been used in order to reduce the experimental effort that will be necessary in later analysis. The number of calibration samples has been reduced by about 60%, the results being comparable to those obtained with a full recalibration.
