| 摘 要： | 建立了电感耦合等离子体发射光谱(ICP-AES)法测定凹凸棒黏土(ATP)中多种金属元素含量的方法,并与火焰原子吸收、原子荧光光谱以及化学分析法对部分金属元素的测定结果进行比较。结果显示,ICP-AES方法线性范围0～2.00 mg/L,相关系数0.999,最低检出浓度0.1～27.5μg/L,回收率92.5%～106.0%,RSD为0.93%～7.6%,测得的结果与其他测定方法相比无显著差异。ICP-AES法简便快速,化学干扰少、结果准确,可以应用于ATP中多种金属元素的含量测定。

| Abstract: | ICP-AES method was established for the determination of multi-metal in attupulgite(ATP) via comparation with the result of by flame atomic absorption spectrometry(FAAS),atomic fluorescence spectroscopy(AFS) and chemical method(CM).The results showed that there was no marked difference between the different methods for the determination of multi-metal in ATP.The linear range of the ICP-AES method was between 0~2.00 mg/L with the correlation coefficient was 0.999 and the minimal detectable concentration was 0.1~27.5 μg/L.The recovery ratio of the method reached 92.5%~106.0%with the RSD was 0.93%~7.6%.ICP-AES method can be used in the determination of the content of multi-metal in ATP due to simple,fast,little chemical interference and accurate result. |
