电感耦合等离子体原子发射全谱直读光谱仪同时测定铅基合金中的银锶钙

Determination of Silver, Strontium and Calcium in Metal Alloy Leadby Inductively Coupled Plasma Atomic Emission Spectrometry

    摘要
  • 摘要: 应用硝酸分解样品, Optima 4300DV ICP同时测定铅基合金中的Ag、Ca、Sr，方法对Ag、Ca、Sr的检出限分别达到0.005、0.06、0.0015 mg/L.经加标回收实验及方法对比试验验证，此方法分析结果准确可靠，能满足铅基合金中Ag、Ca、Sr的测定.

     

    Abstract: ICP-AES was applied for determination of Ag ,Sr and Ca in the metal alloy of lead by samples digested under HNO3. The detection limits were 0.005、0.06、0.001 5 mg/L for Ag,Ca,Sr respectively .The accuracy of the method were demonstrated by the recovery experiments and the comparison with other method .This method can be used to analyze metal alloy samples of lead.
