Determination of Trace Selenium Using Hydride Generation-Silver Selenide Sol Method

Niu Jianjun and Wang Bingwu (Changchun Institute of Applied Chemistry, Acadcmia Sinica)  
A new method for determination of trace selenium has been presented. Se(Ⅳ) was converted into HiSe by reaction with KBH4 pellet in 0.2 mol H2SO4-2% tartaric acid solution and the escaped hydride was absorbed and colored by silver nitrate solution in the presence of gum arabic. Beer's law was obeyed in the range of 0-3 μg Se(Ⅳ)/3ml, the colored solution gave an absorption maximum at 246 mm with detection limit 0.04ppm, most of the foreign ions did not int rfere with the determination of selenium. The method has high sensitivity and selectivity and has been applied to analyse urine selenium yeast and other samples.
