Determination of Phthalates in Plastic Toys by High Performance Liquid Chromatography

CHEN Zhu-ling,CHEN Fei,LIN Xiang-cheng,HUANG Yu-kui(School of Chemistry and Chemical Engineering,Fuzhou University,Fuzhou 350002,China)  
High performance liquid chromatography method was developed for rapid separation and determination of 5 kinds of phthalates(phthalic acid esters)in plastic toys.A separation was performed on a shim-pack VP-ODS column with 4.6mm× 150mm,5μm and CH3OH:H2O(V/V 90:10)with a flow rate of 1.0mL/min as mobile phase and detection wavelength 230nm.Calibration curve was linear in the concentration range of 0.5~1,000mg/L,LOD 0.34~0.96μg/L and mean recovery ranged from 93.00% ~105.23% .The method was used to analyze phthalates in different plastic toys under the optimized conditions of the extraction and purification of samples,with satisfactory results.
