摘要
硫酸亚铁还原/重铬酸钾氧化滴定测铀法是美国新布伦士威克实验室(New Brunswick Laboratory)开发的精密测铀方法,现已被国际标准化组织(ISO)、美国、中国等作为测定U_3O_8、UO_2中铀含量的标准分析方法。在该法中,用重铬酸钾滴定之前必须加入分析纯VOSO_4作催化剂。但是,我国的分析纯VOSO_4产品很少应市,难以购得。
The paper describes the applicability for determination of uranium content with the use of the chemical pure VOSO_4 as a catalyst in the ferrous sulfate reduction/potassium dichromate titrimatric method. The experiment results show that it is necessary to reduce some oxidants in the chemical pure reagent VOSO_4 with Fe^(+2). A method for preparing the catalyst solution using the chemical pure reagent VOSO_4 is presented and its applicability for accurate determination of uranium content was checked experimentally.
