Abstract: The oil soluble organic molybdenum was diluted by organic solvent with certain proportion. The trace element contents in oil-soluble organic molybdenum was determined by inductively coupled plasma optical emission spectrometry（ICP-OES）, such as aluminum, barium, calcium, chromium, copper, iron, potassium, magnesium, manganese, sodium, nickel, phosphorus, lead, silicon, vanadium, and zinc. A simplified and rapid method for the analysis of trace elements in organic molybdenum samples was established. The element spectral lines of samples interfered by Mo were determined by preparation and analysis of samples, and the appropriate analytical spectral lines were selected to eliminate the molybdenum matrix spectral interference. The precision of the established method was investigated, and then the trace elements in the actual samples were determined by the method and the GB/T 17476-1998 method, respectively and compared. The results showed that by the new method, the relative standard deviation of each element was less than 2%, and the spike recovery was 95%-109% at the appropriate spectral line when the oil soluble organic molybdenum was diluted 100 times with ICP diluent. The method is rapid, accurate and is able to determine multiple elements in the oil soluble organic molybdenum simultaneously.
