空气—乙炔火焰原子吸收法快速测定载金炭中银

Air-Acetylene FAAS Rapid Determination of Ag in Carried Gold Carbon

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

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.
