摘要
试样以盐酸和硝酸分解 ,残渣经回收并入原溶液 ,在稀盐酸介质中 ,用火焰原子吸收光谱法测定铜、铅、铁和钙 ,回收率在 95.0 %~ 1 0 5.0 % ,RSD分别为 1 .7%、1 .9%、1 .9%和 4.
The sample is dissolved in HCl and HNO 3. Any insoluble residue are separated and dissolved by further treatment, and the solution is combined with the main solution. An aliquat or whole of the solution is used for the FAAS determinations according to the concentrations of the cations present, RSDs′ obtained are 1.7%, 1 9%, 1.9% and 4.2% for Cu、 Pb、 Fe and Ca respectively. The recoveries are found in the range 95.0%~105 0%.
