Abstract:

Quantitative Analysis of kaolinite by X-ray fluorescence consists of the instrument, sample preparation, measurement, standards and calibration sections. Therein, instrument is Ranger S2, pressed powder pellets method of preparation, addition of PVA solution and standard samples of Vietnam have been investigated and evaluated. Using combined investigation methods as data collecting, standard calibration curve, and knowledge-driven, research results are compared with other results by chemical methods. The accuracy is determined for SiO2, Al2O3, Fe2O3 and K2O in the kaolinite calibration curves are quite good and they are 0.579, 0.67, 0.058 and 0.245, respectively. Moreover, in order to confirm the reliability of standard calibration curve, two kaolinite samples in Lang Dong mine were used for testing analysis by sample preparation procedure mentioned above. The analysis results show that the error of X-ray fluorescence analysis (XRF) and chemical analysis are very low, which confirms the stability and reliability of standard calibration curve and analytical instruments.
