Determination of Major and Trace Elements in Kaolin by X-ray Fluorescence Spectroscopy:Method Optimization and Validation
Kaolin,as an important mineral material,is widely used in fields such as architecture,ceramics,and chemical engineering.However,accurate determination of major,minor,and trace elements in kaolin has always been a challenging and bottleneck issue,crucial for understanding the resource distribution and development and utilization of kaolin.This article takes kaolin as the research object,and through multiple experiments and continuous optimization,a stable,accurate,and economically practical X-ray fluorescence determination method has been established,achieving satisfactory results.The relative errors of the measured elements in kaolin using this method range from-4.50% to 8.71%,and the relative standard deviation(RSD)is≤4.65% .The relative errors of the results compared with standard methods range from-7.69% to 4.17% .This method can also be extended to the analysis of other types of ores,soils,and sediments.
