摘要
用磷酸氢二铵作基体改进剂、塞曼效应石墨炉原子吸收法对地质样中痕量银的测定进行了研究。简化了样品处理过程 ,对地质标样及实际样品分析获得了满意的结果 ,加标回收率为 91.2 %～ 99.8% ,相对标准偏差为 6 .5 %～ 7.7%。所拟定的方法快速、简便。
Taking (NH 4) 2HPO 4 as a matrix modifier,a method for determination of trace silver in geochemical samples by Zeeman graphite furnace atomic absorption spectrometry was studied.The proposed method simplified the procedure for sample processing.Satisfactory results were obtained in determination of trace silver in geochemical reference and practical samples.The recovery was in the range of 91.2%～99.8% while the relative standard deviation was in the range of 6 5%～7 7%.The proposed method is quick,simple and accurate.
