| Abstract: | A method for determination of Na in zeolite by flame atomic absorption spectrometry(FAAS) after dielectric assisted microwave digestion for sample preparation was developed,with the recovery between 92%～102%.Assisted by dielectric,digestion,evaporation and cooling could be done in a single vessel by one step,so it was fast,clean and safe. |
