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.
