摘要
目的:建立皂矾及煅皂矾中铁、砷的测定方法。方法:根据各自特性,建立皂矾中砷盐定性检测,采用铈量法测定皂矾中硫酸亚铁(FeSO_4)的含量,采用EDTA滴定法来测定煅皂矾中三氧化二铁(Fe_2O_3)的含量。结果:定性检测反应灵敏,定量测定中,皂矾、煅皂矾的加样回收率分别为99.7%和98.87%,RSD分别为0.28%和0.73%(n=5)。结论:本法简便易行,结果准确,可作为控制其质量的依据。
Objective：To establish the methods of determination of Fe,As in melanteritum and calcined melanteriturn. Methods： According to their individual characteristics, to establish the methods of the identification and determination of content by cerium sulfate method and EDTA compleximetry. Results ： The identification was sensitive. The average recovery of melanteritum and calcined melanteritum were 99.7% （ RSD = 0. 28% ） and 98.87% （RSD =0. 73% ）,respectively. Conclusion： The methods are simple and accurate. It can be used as quality control .
