| Abstract: | In situ X ray fluorescence analysis may be subjected to some interference factors, such as matrix effect, humidity and unevenness effect. This paper employs the Intensity Influent Coefficient Method and the Characteristic to Scattering Ratio Coefficient Method for the correction of matrix effect, the Scattering Correction Method for the humidity effect, and Characteristic to Scattering Ratio as the basic parameter for unevenness. All these means have been integrated in a portable multi element XRF analyzer. The analyzer and the techniques were successfully applied to determining concentrations of K, Ca, Ti, Mn, Fe, Cu, Zn, Sr, Pb, in rock outcrops and soil of four copper prospecting areas and have been proved to be of high efficiency and low cost. |
