摘要
探讨了50μg以下的硒与氢氧化铁共沉淀的因素和分离铅基合金中硒的条件,从而成功地利用催化极谱法测定铅基合金中硒.分析范围在0.05%～0.0005%,回收率在91.5%～105%间.方法操作简便,快速准确,使用试剂量少,成本低,易于推广.应用于铅基合金中硒的测定,获得满意的结果.
The optimum conditions for the separation of less than 50μg of Se in lead base alloys by co-precipitation with Fe(OH)3 was studied. The determination was than carried on by the catalytic polaro-graphic method. The range of determination is 0. 05%-0.0005%. The recovery is 91. 5%-105%. This method is simple and easy to master.
