摘　　要：采用电感耦合等离子体质谱法（ICP-MS）测定船用润滑油中元素钼、镍、钒、钛、钡、镉、铜、铅和锰。油液样品经加热蒸发和高温灼烧灰化处理,再加硝酸和过氧化氢湿法消解,消除了有机质对质谱测定的影响。经过优化仪器工作条件,内标校正和干扰方程处理后,所测定元素的标准曲线相关系数达0.9999以上,加标回收率为93~106%,RSD〈1%。Trace elements molybdenum,nickel,vanadium,titanium,barium,cadmium,copper,lead and manganese in marine lubricant were determined by inductively coupled plasma mass spectrometry（ICP-MS）. The oil samples were heated to evaporate afer ashing treatment at high-temperature buring. The residue was digested in the mixture of nitric acid and hydrogen peroxide,above sample treatment completely eliminated the interference of organic matter on mass spectrometry measurement. Optimization of instrument conditions,internal calibration and interference equation,the correlation coefficient of standard curve was reached to 0.9999,the recovery of the measuring elements were 93~106% and RSD1%。
