摘　　要：本论文确定了X射线荧光熔片法测定超基性岩中Si、Ca、Fe、Ni、Co、V等14种主次量元素的方法。样品与助溶剂比例为1∶10,样品在700℃预氧化,1050℃预熔2 min,旋转、摇摆10 min,铂-黄金坩埚自然冷却制备玻璃样片。用国家一级标准物质和人工混合标样制备校准标准样片,建立校准曲线,用熔片法大大降低了矿物效应和粒度效应,用经验系数法补偿基体效应,检测元素除Co相关系数r=0.99665外,其他元素相关系数均大于0.999,本方精密度、准确度法满足化学分析要求。The method of measuring Si,Ca,Fe,Ni,Co,and V in X-ray fluorescence melting method was determined.The ratio of sample to cosolvent was 1∶10,the samples were pre-oxidized at 700℃,premelted at 1050℃for 2 min,rotated and rocking for 10 min,and naturally cooled with platinum-glass crucible.The calibration standard sample is prepared by national level standard material and artificial mixed standard sample,and the calibration curve is established,the mineral effect and particle size effect is greatly reduced by melting method,the matrix effect is compensated by empirical coefficient method,except Co correlation coefficient r=0.99665,the correlation coefficient is greater than 0.999.The precision and accuracy method meet the requirements of chemical analysis.
