【Abstract】 Partial least squares(PLS) spectrophotometry has been proposed for 8 hydroxyquinoline complexcolorating system. As an available indirect multirariate calibration method, PLS is employed to tread a four component mixture system. Which is composed of Cu, Pb, Cd, Co complex compound. Good average recoveries and relative standard deviation are obtained.更多还原
