摘 要：
混合碱的测定方法采用双指示剂法,由于该法指示剂指示终点误差偏大,而采用氯化钡法来测定混合碱,将氯化钡法中所用的甲基橙指示剂改为改良甲基橙指示剂,并选择0.1 mol/L氯化钡加入量以过量20%,进行氯化钡法测定混合碱的条件探索,以提高分析结果的准确度和精密度。

摘 要：
With much margin for error in the terminal indicator when using the double indicators method in the measurment of hybrid alkali,we adopt the Chlorination barium method,exploring its condition quest in hybrid alkali measurement so as to raise the degree of accuracy the analysis result.
