| Abstract: | By use of multiple linear regression analysis to ion-selectrode,determinations of two component of cadmium and lead concentrations have been established.The least square method to determinating lead and cadmium according to the direct electric potential method are discussed.Meanwhile,the regression equation are established,six of quaternary mixed samples are determined,and satisfactory results are obtained. |
