摘要
为了方便检测Al-Ni合金粉碱洗液中含NaAlO2和NaOH浓度,用EDTA络合铝离子,再用标准氯化锌溶液返滴定测量铝含量,用盐酸滴定NaOH。本方法再现性好,简单方便,满足现场分析配合要求。
In order to facilitate the detection AI-Ni alloy powders base lotion contains NaAIO2 and NaOH concentration, with EDTA complex aluminum ions, and then use standard zinc chloride solution back titration measurement of aluminium content, with hydrochloric acid titration NaOH. This method repeatability is good, simple and convenient operation, meet with the requirement analysis.
