Determination of Major Elements in Kaolin by Ultrafine Powder Tablet X-ray Fluorescence Analyzer
The standard material of kaolin(including internal control samples)was crushed to micron level by ultrafine grinding technology,and the working curve of kaolin by X-ray fluorescence spectrometry of ultrafine powder tablet was established to overcome the particle size effect and mineral effect.The main element content of kaolin was determined by deducting the calibration of the lost content,and the result of the standard material determination was consistent with the standard value by normalized calculation.The method has high accuracy and good preci-sion,and greatly improves the detection efficiency of kaolin.The recovery rate of main element aluminum is between 92.00%and 110.00%,which meets the requirement of main element detection of kaolin and reduces the pollution to the environment.
