To simultaneously and efficiently extract pollutants with differential polarities, we herein fabricated and characterized a multifunctional nanocomposite. The novel nanohybrids used NiFe2O4 as magnetic cores, and NH2-MIL-101(Al), β-cyclodextrin and graphene oxide as functional components combined with magnetic cores. With the aid of graphene oxides large π-conjugated system, NH2-MIL-101(Al)s strong adsorption to moderately/strongly polar chems., and β-cyclodextrins specific recognition effect, the nanohybrids realized synergistically efficient extraction of polyaromatic hydrocarbons and bisphenols with a logKow range of 3-6. Combined with acidic and alk. sources, the nanohybrids-based effervescent tablets were prepared Based on effervescent reaction-enhanced nanohybrids-based efficient adsorption/extraction and high performance liquid chromatog. and fluorescence detection, we successfully developed an excellent microextraction method for the simultaneous determination of both polyaromatic hydrocarbons and bisphenols in roasted meat samples. Several important variables were optimized as follows: Na2CO3 and tartaric acid as acidic and alk. sources, 900μLof the mixed solvent (acetone and hexane at 2:1 by volume/volume) as the eluent, 5 min of elution time. Under optimized conditions, the novel method gave low limits of detection (0.07-0.30μg kg-1), satisfactory recoveries (86.9-103.9%), and high precision (relative standard deviations of 1.9-6.7%) in roasted lamb, beef, pork, chicken, and sausage samples. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Synthetic Route of C13H12O2).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Synthetic Route of C13H12O2
