[Principle and application of scattering power function method in X-ray fluorescence analysis. III. Continuous scattering radiation].
The study in this paper shows that the relationship between mass attenuation coefficient and continuous scattering radiation at wavelength 0.081 nm is not an inverse proportion supposed as the scattering internal standard method but a power function in a wide range of matix composition. Experimental results are in good agreement with that of theoretical prediction. A new method is recommended for matrix absorption correction using the 1.22 power function of continuous scattering radiation at wavelength 0.081 nm and used for microelement Sr determination in geological samples as an application example. The accuracy of the results by this method is nearly 4 times better than that from the traditional scattering internal method in a wide range of matrix composition.
