Resumen
A simple and low cost method to determine volatile contaminants in post-consumer recycled PET flakes was developed and validated by Headspace Dynamic Concentration and Gas Chromatography-Flame Ionization Detection (HDC-GC-FID). The analytical parameters evaluated by using surrogates include: correlation coefficient, detection limit, quantification limit, accuracy, intra-assay precision, and inter-assay precision. In order to compare the efficiency of the proposed method to recognized automated techniques, post-consumer PET packaging samples collected in Brazil were used. GC-MS was used to confirm the identity of the substances identified in the PET packaging. Some of the identified contaminants were estimated in the post-consumer material at concentrations higher than 220 ng.g-1. The findings in this work corroborate data available in the scientific literature pointing out the suitability of the proposed analytical method. 30 4 1046 1055 Adams, R.P., (1995) Identifcation of Essential Oil Components By Gas Chromatography/ Mass Spectrometry, p. 698. , Carol Stream: Allured Bayer, F.L., Polyethylene terephthalate recycling for food contact applications: Testing, safety and technologies: A global perspective (2002) Food Additives and Contaminants, 19, pp. 111-134. , Supplement Portaria SVS/MS no 987, de 8 de dezembro de 1998.
