| 摘 要： | 把线性法应用于沉淀滴定反应中终点的确定。利用电位滴定手段，分步等量地加入滴定剂，测量对应电位。等当点可用人工作图法确定，也可以借助于计算机进行线性回归来确定。利用线性滴定法代替传统的沉淀滴定法，测定过程简便迅速。

| Abstract: | A linear method for the determination of the end points in the reaction ofprecipitation titration is presented. The equal volumes of titrant are added stepwise by the use ofpotentiometric method and measure the correspondent potential. The equivalent points can bedetermined by manual graph or by the linear regression with computer. The merit of thismethod is the utilization of linear titration plot instead of the conventional precipitation titrationcurve. And the procedure of determination is simple and rapid. |
