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 CH_3OH : H_2O (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.
