3 Method summary

Samples were burned to remove the pre-crystallization of water, the sample is ignited prepared borate glass melt samples, using X-ray fluorescence spectrometry Analyte measured X-ray fluorescence intensity was measured at baseline background characteristic line near the location of the sample as background subtraction. With Alumina base material, lead, cadmium, chromium standard solution, prepared using standard samples. Application of the principle of inter-α-factor correction correction element matrix effect correction Line strength and concentration to do after being fitted by a linear least-squares method. Determination results of samples obtained after the correction of loss on ignition in the original sample content.
