摘　　要：采用多元线性回归分析结合离子选择电极法,解决了离子选择电极测定元素含量时共存离子干扰的问题,实现了日用陶瓷铅、镉溶出量的快速、同时测定。测试结果与国标中规定的原子吸收分光光度法相比,相关系数趋近于1,并且成本低廉,仪器轻便,测试快速。By using multiple linear regressions combining with the ion-selectrive electrode method,the problem of coexisting ions interference is solved,and the method for determination of the releasing of lead and cadimium in domestic ceramics is realized.Compared with atomic absorption spectrophotometry method in national standard,the correlation coefficient between these two method results is close to 1.Besides,the method presented in this paper has characteristics of low cost,portable instrument and fast testing.
