A simple, rapid determination of phthalate esters plasticizer in leather products byHPLC method was developed and evaluated.Phthalate ester plasticizers in leather products were extracted by using cyclohexane as solvent. The extraction was analyzed by HPLC. According to the possible existence ingredients, two kind of quantitative analysis methods were chosed; With the combination of two quantitative analysis methods,, Quatitative curve with good isolation, smooth baselineand repeatability could be achieved. The detection limits are 2 mg/kg for DNP and DNOP,and less than 0.20 mg/kg for the other 20 kinds of phthalate plasticizers. The spiked average recovery varies from 90% to 101% and the relative standard deviation (RSD) of precision experiment is all less than 7%.The proposed method can fully meet the determination requirement of phthalate esters plasticizer in leather products.
