【摘要】样品经灰化,王水溶解后,直接用原子吸收法测定银,方法快捷、准确,经济,精密度小于等于3%,回收率为97.0%～101%,用于多种载金炭中银分析,结果令人满意更多还原

【Abstract】 The sample was ashed and dissolved in aqua regia, then directly determined silver with flame AAS. The method was quick,accurate and economical. The relative standard deviation was ≤3.0 % and the recovery was 97.0 %～101 %. The method has been applied to determine Ag of many kind of Carried Gold Carbon with satisfactory results.更多还原
