摘　　要：介绍了自动电位滴定法测定白液中的总碱、活性碱和有效碱,与传统的白液测定方法相比,滴定中不加有毒物质氯化钡和甲醛,直接连续滴定,通过pH值判断滴定终点,操作简便,检测速度快,准确度高。The automatic potential titration method for determining total alkali, active alkali and effective alkali in white liquor was introduced. The method can titrate directly continuously without adding agents such as BaC12 and formaldehyde as the conventional method, the end point of titration can be easy to judge from pH value. The method has advantages of easy operation, quick determination and high accuracy.
