摘要
本文藉以在盐酸羟胺存在下,在标准系列中加入不含金的样品溶液作试剂空白,用TMK—Au—十二烷基苯磺酸钠(DBSASS)生成的三元络合物,不经过分离能直接测定含铁试样中的金。实验表明,在此条件下能消除20mgFe(Ⅲ)的干扰。与其它方法对照结果令人满意。该法操作简单、快速、能测定含铁试样中0.5g/T以上的金。
This peper reports that in hydroxylamine hydrochloride the tribasic coordination complex TMK--Au--DBSASScan be used directly in the determination of more than 0.5g/T gold in iron samples without any separation. It hasbeen shown that this method is simple, rapid and not interfered by 20 mg Fe(Ⅲ). Compared with other method, theresult obtained is satisfactory.
