| 摘 要： | 样品经硝酸、氢氟酸、高氯酸分解，制成硝酸溶液，经巯基棉层析柱过滤富集Ag，并用2mol／LHBr溶液洗脱，用火焰原子吸收法测定洗脱液中的Ag和滤液中的Cu，Pb，Zn。用该法测定化探样品中银和铜铅锌，检出限低，结果准确度和精密度均令人满意。

| Abstract: | The sample through the dissolution in NHO3 acid, HF acid and HC1O4 is made into the nitric solution. By making use of the mercapto cotton to filter out the Ag of enrichment and then fulfilling washing desulfuration in 2mol/ L hydro - bromine, flame atomic absorption method is put to determine Ag in washing desulfuration resolution and Cu, Pb, Zn in filtrate. This method in mensurating Ag and Cu, Pb, Zn is of low detection limit and accurate results. |
