摘要
描述了以硫酸肼为还原剂,磷酸三丁脂(TBP)为萃取剂,用亚化学计量法测定微克量铊的方法.测定量在5~100μg范围内,测定铊的精确度>±1.6%.
A method is studied for the determination of microgram quatities of thallium by substoichiometric reduction of Tl^(3+)with hydrazine sulfete. Separation of the two oxidation states by extraction of the former into TBP(tributyl phosphate). The experimental results show that thallium can be determined in the 5~100μg range with the error±1.6%.
