摘要
将多元线性回归分析应用于离子选择电极分析法中,同时测定了混合物重金属铅、镉离子两组分的含量.讨论了最小二乘法应用于测定两组分的原理及方法,讨论了直接电位法测定铅、镉离子的最佳实验条件,建立了回归方程,对6个混合样进行了测定,获得满意结果.
By using the multiple linear regression analysis to ion-selectrode,determinations of two component of cadmium and lead concentrations are established.The principle and method by use of the least square method for determinating lead and cadmium are discussed according to the direct electric potential method.Meanwhile,the regression equation is established,six mixed samples are determined and satisfactory results are obtained.
