| Abstract: |
| Objective To establish an effective detection method of dioctyl phthalate(DEHP) migration contained in Chinese decoction packing materials. MethodsCOSMOSIL 5C18-AR-Ⅱ (4.6ID × 150mm) C18 chromatogram column separation was performed with mobile phase of acetonitrile, methanol and water (90∶10∶0.5), sample size of 20μl (for control) and 40μl (for sample), flow rate of 1.0ml/min, column temperature of 30 ℃ and detection wavelength of 224nm. The amount of DEHP migration after filling was detected. ResultsMass concentration and peak area from each component had good linear relationship （r=0.99949）, and the DEPH component was separated within 15min. Detection limit was 1.534566mg/L with average recovery of 101.4070%. The instrument precision relative standard deviation was 0.501%, method relative standard deviation (RSD) was 2.101%. ConclusionThe established method is sensitive and convenient, suitable for detection of dioctyl phthalate migration contained in Chinese decoction packing materials. |
