摘要
介绍了油样经过灰化、酸溶后，通过加抗干扰剂消除共存磷等的干扰，用空气－乙炔火焰原子吸收光谱法测定润滑油中钙含量的方法。与化学法比较，相对误差小于５％，回收率１００％，相对标准偏差小于５％。
Calcium content in lube oil was determined by AAS with airacetylene flame after the oil sample was ashed,dissolved with acid,added interferencefree reagent to eliminate the interference from phosphorus.Compared with chemical method,the relative error and the relative standard error are below 5 per cent,the recovery rate reaches 100 per cent.
