The work aims to evaluate the migration risk of vinyl chloride, vinylidene chloride and 1,1-dichloroethane from food contact recycled polyvinyl chloride materials. A gas chromatography method was developed to determine the migration of vinyl chloride, vinylidene chloride and 1,1-dichloroethane in food contact recycled polyvinyl chloride materials in water, acid, ethanol, olive oil and chemical alternative solvents. The three substances were separated on a DB-624 (60 m×250 μm×1.4 μm) capillary column, and detected with an electrical conductivity detector (ECD). Results showed that vinyl chloride, vinylidene chloride and 1,1-dichloroethane had good chromatographic separation effect and there were good linear relationships for the analytes in the range of 0.005-0.05 mg/kg, with a detection limit of 0.001 mg/kg and a quantitation limit of 0.005 mg/kg. When the addition amounts were 0.005 mg/kg, 0.01 mg/kg and 0.02 mg/kg, the recoveries ranged from 94.8% to 108%, with the relative standard deviations (n=6) of 0.0%-9.0% which was lower than 10%. With high accuracy and good precision, the established method could be used to determine the migration of vinyl chloride, vinylidene chloride and 1,1-dichloroethane in food contact recycled polyvinyl chloride materials.
