Synthesized polypyrrole-coated Fe3O4 magnetic nanoparticles have been successfully characterised and applied as sorbent for the magnetic-micro-dispersive solid-phase extraction of eleven phthalic acid esters from jelly and apple-based beverage matrixes widely consumed by the population and, especially, by children. Sorbent was synthesized through chem. coprecipitation and subsequently characterised by different techniques. The influence of several parameters on the extraction efficiency was exhaustively evaluated using a step-by-step strategy. The separation and quantification of the selected phthalates were performed by ultra-high performance liquid chromatog. coupled to tandem mass spectrometry. The validation of the methodol. was carried out for jellies and apple-based beverages, employing dihexyl phthalate-3,4,5,6-d4 as the surrogate standard Relative recovery values were in the range 70-114% for both matrixes and relative standard deviations below 20% were obtained. The limits of quantification of the method were found in the range 0.147-0.416 娓璯/L. Feasibility of the developed methodol. was proved by the anal. of commercialised jelly and apple-based beverage products. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Application of 84-61-7).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Application of 84-61-7
