研究了用电感耦合等离子发射光谱仪(ICP-AES)内标工作曲线法测定润滑油中钙含量的分析方法。通过选择合适的内标物及实验条件,方法的标准偏差为2.2%,钙回收率为96%~104%,可以用于测定润滑油中的钙含量。
The analytical method for the determination of calcium in lubricating oil by ICP-AES internal standard curve method was studied. The standard deviation of the method was 2.2% and the recovery rate of calcium was 96% ~ 104% by selecting suitable internal standard and experimental conditions, which could be used to determine the calcium content in lubricating oil.
