| Abstract: | A method for the quantitative determination of chemical elements in Montmorillonite by Rigaku 3080 E3 model XRF spectrometer with cellophane glue-paper as a substrate of powder has been performed successfully. The transmission method was used to reduce the background scattering intensity , the amount of sample only needed about 10 mg, and the precision of specimen preparation and measurement was better. The analytical results for the standard sample and spceimen by this method conformed with their certified values and AAS method. This method was characterized by simplicity, rapidity, accuracy and low-cost and suitability for minor sample and monomineral analysis. |
