主　　题：Raman spectroscopy co-precipitation heavy metals partial least squares regression 

摘      要：Mn co-precipitation method combined with Raman spectroscopy were used to detenmine trace heavy metals(copper,zinc,cadmium and lead)in water *** concentrations of heavy metals including copper,zinc,cadmiun and lead in water samples were separated and enriched by Mn^(2+)-phen SCN-ternary complex 0o-precipitation *** Raman spectra of co-precipitation sediments were collected using confocal micro-Raman *** preprocessing treatments and regression calibration methods were *** best models using partial least squares regression(PLS)of copper,zinc,cadmium and lead were built with a correlation cofficient of prediction(R_(p))of 0.979,0.964,0.956 and 0972,respectively,and the root mean square error of prediction(RMSEP)of 6.587,9.046,9.998 and 7.751 pug/kg,*** co-precipitation procedure combined with Raman spectroscopy method are feasible to detect the amount of heavy metals in water.
