摘要
本文采用盐酸－硫酸在烧杯中加热分解氢氧化铝，以ＥＤＴＡ络合Ａｌ３＋，过剩ＥＤＴＡ用锌盐回滴，从而直接测定工业氢氧化铝中Ａｌ２Ｏ３含量。方法简便快速，不用昂贵铂器皿及设备，结果满意。
In this paper,a method determining directly the Al2O3 content in technical--purtity aluminium hydroxide is presented, which adopts heat--decomposing aluminium hydroxide with hydrochloric acid-sulphuric acid mixture solution,takes EDTA as complexing agent of Al3+,and titrates the excessive EDTA in return with zincate. The method is simple,convenient,and quick without expensive platinic utensils and equipments. The analytical results are satisfactory.
