摘要
用石墨炉固体进样技术直接测定岩矿样品中微量银,用正交设计法进行测试参数的选择;采用氘灯及人工合成模拟样品基体扣除背景;使用了平台技术及自制进样器,以多种方法成功地测定了岩矿样品中的微量银。不同方法结果基本吻合。
A new method for direct determination of trace silver in solid rock or mineral samples by graphite fumace AAS is developed. In this proceclure, sample feeding is corrected by D_2 lamp and synthetic sample matrix. The detection limit and characteristic mass are 0.079μg/g and 0.456pg/0.0044 AILS. S, respectively. The accuracy of determination is less than 15% and the relative error is concodant with that of other methods.
