摘要
采用HNO3消解与微波消解相结合的样品预处理方法,利用火焰原子吸收光谱仪测定某推进剂中金属元素Pb、Cu和Ca的含量。结果表明,各分析元素的回收率为99.38%~100.60%,相对标准偏差(RSD)为1.13%-3.23%(n=5),该方法简便快速、准确可靠。
A new method for respective determination of Pb,Cu and Ca in a propellant sample was proposed by flame atomic absorption spectrometry with the microwave assisted digestion to the sample digested by HNO3. The results of determining Pb, Cu and Ca in the propellant samples, show that the RSDs( relative standard deviations) are in the range of 1.13% -3.23% (n = 5 ) and the recovery is 99.38% - 100.60%. The method is simple, rapid and highly accurate.
