Abstract: Inductive coupled plasma atom emission spectra (ICP-AES) analysis for main and trace elements of zeolite was studied.Influences of acidity of dissolved sample and instrument conditions on determination and the interfering among coexisting elements were investigated.Working conditions were also optimized.Results showed that the relative standard deviation (RSD) of main elements was less than 1%,and  recovery rate was 98.6%;and the RSD of trace elements was less than 7%,and recovery rate was at 85%~112.1% . 

Key words: ICP-AES, beta zeolite, main elements, trace elements
