The sample was extracted with 007 mol/L hydrochloric acid.Migratable chromium in the extract was determined by inductively coupled plasma mass spectrometry（ICP-MS）.Some other extract was taken and the high content of interferential positive ions was removed by co-precipitation method with aluminium nitrate.Then Cr（Ⅵ） in the extract was determined by ion chromatography-inductively coupled plasma mass spectrometry（IC-ICP-MS）.Cr（Ⅲ） content was obtained by minusing Cr（Ⅵ） content from the total migratable chromium content （Cr（Total））.The method quantitation limit for Cr（Total） and Cr（Ⅵ） reached to 0.01 mg/kg and 0.003 mg/kg,respectively.The method was then validated by conducting standard-addition experiments to the difference categories of toy materials according to Toy Safety Directive 2009/48/EC.The recoveries of Cr（Total） and Cr（Ⅵ） from the standard-addition experiments were in the ranges of 90.2%-101.5% and 96.7%-1067%,respectively, and the inter laboratory relative standard deviations were less than 7.4% and 7.9%,respectively.Therefore,the method was concluded to be accurate and reliable,which could satisfy the requirements of Cr（Ⅲ） and Cr（Ⅵ） in 3 categories of toy materials of Toy Safety Directive.
