Development and validation of a multi-analyte GC-MS method

Human exposure to chemicals from food contact materials (FCM) occurs mainly as a result of migration from materials into foodstuffs. The extent of this migration is one of the key factors for the human health risk which a packaging material could represent [ 1 ].

Determination of phthalate acid esters plasticizers in

A method for the analysis of phthalic acid esters or (PAEs) in polyethylene terephthalate (PET) bottles based on the use of microwave-assisted extraction (MAE) and liquid chromatography with UV detection (LC-UV) was developed. The microwave-assisted extraction procedure was optimized by a three factors Box¨CBehnken response surface design.

Microplastic acts as a vector for contaminants: the release

The pollution of contaminants brought by plastic fragments is worth paying attention in the study of microplastic. The additives, like phthalates (PAEs), introduced during manufacture, are physically dispersed and can easily release into environment. Polyvinyl chloride pipes are widely used in China, and DBP is also a typical kind of additives in PVC materials. Here, the release behavior of

The catalytic performance of Fe (¢ò)-MOFs was were obtained by the experiment of degrading dibutyl phthalate (DBP) through persulfate activation. It was found that the degradation efficiency of 0.018 mmol L?1 DBP was 86.73% under the conditions of 0.40 g L?1 and 2.70 mmol L ?1 persulfate at a wide pH range.

Abstract. A significant increase in the production of plastic materials and the expansion of their areas of application contributed to the accumulation of a large amount of waste of polymeric materials. Most of the polymer composition is made up of plasticizers. Phthalate plasticizers have been recognized as potentially hazardous to humans and
