摘要
高岭土作为一种重要的矿物材料,广泛应用于建筑、陶瓷、化工等领域.然而,高岭土中的主次痕量元素含量的准确测定一直是一个难点和瓶颈问题.为准确和快速测定高岭土中各组分含量,达到高效利用高岭土资源的目的,通过多次实验和不断优化,建立了一套稳定、准确、经济实用的X射线荧光光谱测定方法,并取得了较为满意的结果.使用该方法测量高岭土中的多种元素的相对误范围在-4.50%～8.71%,相对标准偏差(RSD)≤4.65%,本法与标准方法各元素测定结果的相对误差范围在-7.69%～4.17%.本法还可以拓展为其他类型矿石、土壤和沉积物等样品的测试方法.
Abstract
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.
