| Abstract | OBJECTIVE: The isotope dilution method for determination of 18 phthalic acid esters(PAEs) plasticizer in four kinds of food simulants were developed. METHODS: 18 PAEs were extracted by hexane in water, 3% (W/V) acetic acid and 20% ethanol of food stmulant. The 95% ethanol of food simulant was diluted to 20% ethanol by water and then was extracted by hexane. RESULTS: The linear range of DINP and DIDP were 0.2 - 5.0 mg/L meanwhile the DMEP, DEEP and DBEP were 0.02 -2.0 mg/L, the other 13 PAEs were 0.005 -2.0 mg/L, the relative coefficients were greater more than 0.9991 by internal standard calibration. The limit of detection of 16PAEs were 0.1 - 6.7 mug/L, DIDP and DINP were 200.0 mug/L. The average recoveries were from 85.3% to 115.0% with RSD less than 10%. CONCLUSIONS: Compared with the previous national standard method, the detection series of phthalic acid esters were expanded. The stability of the test results were solved in simulant 95% ethanol. The method is simple and repeatable by isotope dilution statutory quantitatively. |
