摘要
目的:建立原子吸收分光光度法测定羧甲纤维素钠中的铅、铜含量的分析方法。方法:样品经微波消解,采用石墨炉法测定铅含量,火焰法测定铜含量,并对测定方法进行了方法学考察。结果:方法线性关系良好,相关系数r>0.999,精密度试验RSD为1.6%~3.0%,平均回收率为90.1%~92.1%。结论:该方法准确,稳定且无干扰,可较好地用于羧甲纤维素钠铅、铜的含量测定。
Objective：To establish an Atomic Absorption Spectrometry method for determination of Lead, Copper in Carboxymethylcellulose Sodium. Method：Samples was digesed with microwave digestion system, and the Pb were determined by graphite atomic absorption spectrometry （GFAAS）; the Cu were determined by flame atomic absorption spectrometry （FAAS）and examine the reproducibility and recovery of the method. Result：It was a good linear relationship, and r〉0.999, RSD was 1.6%-3.0%, and the average recovery rate was 90.1% -92.1%. Conclusion：The method is accurate and stable, can be used for the determination of Lead, Copper in Carboxymethylcellulose Sodium.
