DEHP Migration from Solid PVC Discs Soaked in Groundnut Oil: Experimental Study and Mathematical Simulation

Authors : Badria Bouchelaghem and Djelloul Messadi

Abstract: The use of labelled DEHP and radioactivity measurements in conjunction with weight loss give quantitative information on the mass exchanged when plasticized PVC discs are soaked in groundnut oil and lead to DEHP concentration profiles that are developed through the bulk of polymer during the process. Low penetration advantage of the edible oil within the PVC samples in order to test a simplified mathematical model is considered. Mathematical simulation led to correct figures of migration and it is all interesting since it requires measurements at short times. Rapid determination of the quantity transported after infinite time is the principal difficulty in this kind of study. This last constraint can be get round, while using thinner discs plasticized at high rates.
