Determination of phthalate esters content in plastic articles: Comparison of extraction methods

  • Monika Gawlik-Jędrysiak


Two variants of solvent extraction method (by Soxhlet and ultrasonic) for phthalate esters (DEHP) recoveries in PVC samples were compared. Solvent and extraction time for both techniques were also studied. DEHP content was quantified by GC-MS. The results obtained were compared using statistical methods (LSD test, t-test). 16-Hours DCM Soxhlet and 2-h DCM ultrasonic extraction methods were more convenient with respect to recovery, precision and practicability.
