Abstract：Theanalysis methodfor thedeterminationofCaOand MgOelements inconverterslag eliminationagentby ICPOES methodisproposedinthearticle.Theinfluenceofthedissolutionmethod，theelementspectralline，thesamplequantity，and thespectralineinterferene wereinvestigated，andthebest workingconditionoftheinstrument wasdetermined.The 315.887nm calcium oxide and 285.213nm magnesium oxidespectral lines wereselected.Becausethere is no relevant standard material，the high purityalumina powder makesaseries of workingcurves，andthespikerecoveryrate isused to verify the accuracy of the method.The recovery rate of 1l groups of data is between 95% and 101% ：
