络合滴定法在分析化学中开始应用后,测定常量铝的其它方法很快为络合滴定法所取代。但这并不能说明络合滴定测定铝在当时就具有很高的实用价值,因为络合滴定测定铝的选择性还是很不理想的。自Sajo~1提出用氟化物置换铝—EDTA络合物后,络合滴定测定铝的选择性才进入一个新阶段。因而该法才具有较高的应用价值。络合滴定测定铝已有专文作过评述,本文将简略地总结近年来络合滴定测定铝的现状。尤其是我国分析工作者所作的努力与取得的成绩,引起广大分析工作者的注意,以期今后取得新的成绩。EDTA首先被用于铝的络合剂,有 After complexometric titration began to be used in analytical chemistry, other methods of determining constant aluminum were quickly replaced by complexometric titration. However, this does not mean that complexometric titration of aluminum has a high practical value at that time because the selectivity of the complexometric titration of aluminum is still not very satisfactory. Since Sajo ~ 1 was proposed to replace the aluminum-EDTA complex with fluoride, the selectivity of the complexometric titration of aluminum was measured before it entered a new phase. Thus the law has a higher value. Complexometric titration of aluminum has been discussed in the article, this article will briefly summarize the status of complexometric titration of aluminum in recent years. In particular, the efforts made and the achievements made by the analysts in our country have drawn the attention of a large number of analysts with a view to achieving new achievements in the future. EDTA was first used in aluminum complexing agents, there
