Resumo

ADIPATE UTILIZED AS PLASTICIZERS IN PVC FILMS.The validation of analytical methods was carried out for di-(ethylhexyl) phthalate (DEHP) and adipate (DEHA) the determination of in PVC films.The level of DEHP and DEHA in samples was determined by leaving the film in contact with n-heptane during 48 hours and analysis in a gas chromatograph (GC) equipped with a flame ionization detector and fused silica column with 5% phenylmethyl silicone in the dimensions 30 m x 0.53 mm x 2.65 mm.The results for detection and the quantification limits were smaller than the restriction limits.The recovery rates of DEHP and DEHA were, respectively, 69.10 and 75.30%.
