Evaluation of solid-phase microextraction as an alternative official method for analysis of polymers migration. The objective this study was to compaire the official methods with solid-phase microextraction (SPME)for the analysis of compounds migrating from cross-linked polyethylene into water. A medium polarity polydimethylsiloxane/divinylbenzene (PDMS/DVB)was proved most efficient for the SPME extraction. However, when applied to water samples in contact with polyethylene, SPME proved to be immensely more sensitive and have a greater extraction range than liquid-liquid extraction (LLE). It was proved the migration of Phenol, 2,4-bis(1,1-dimethylethyl). Concentration of this compound 0,6-0,15mg/l.It was proved the migration of Cyclohexadiene-1,4-dione, 2,6-bis(1,1-dimethylethyl).
