|Title:||A Method To Determine Volatile Contaminants In Polyethylene Terephthalate (pet) Packages By Hdc-gc-fid And Its Application To Post-consumer Materials [determinação De Contaminantes Voláteis Em Embalagens De Polietileno Terefalato (pet) Por Cdel-cg-dic E Sua Aplicação A Materiais Pós-consumo]|
|Abstract:||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.|
