摘　　要：介绍了用空气-乙炔火焰原子吸收法测定润滑油添加剂二烷基二硫代磷酸氧钼中的w(有机钼),通过实验确定了用空气-乙炔火焰法测定钼的最佳实验条件。此方法在0～60μg/mL成线性,检出限为1.0μg/mL,相对标准偏差小于1.7%,加标回收率为97.5%～100.8%。Determining method for organic molybdenum content in lube oil annexing agent which is oxygen molybdenum dialkyldithiophosphate has been established by air-acetylene flame atomic absorp tion spectrometry. The experimental optimum condition has been determined by making experimentson it. The method appears good linearity in 0 ～60μg/mL concentration range,it has a detection limit which is 1.0μg/mL. The relative standard deviation of the method is less than 1.7%,and the recoveryis between 97.5% and 100. 8%.
