DBS-偶氮胂光度法测定微量铀的研究与应用

Determination of trace U by spectrophometry of DBS-Arsenazo

研究了在H3PO4介质中,以TiCl3为还原剂的U(Ⅳ)与DBS-偶氮胂反应的条件及配合比,样品分析结果证明:该方法可满足微量铀分析要求。

This essay is a study on the conditions and ratio of reaction eomplexing between U （Ⅳ） and DBS-arsenazo in the solution of phosphate, with reductant of TICl3. The analysis result of samples shows that this method can he applied to determine trace U.
