Abstract

The invention provides an adsorbent, a preparation method and application thereof. The adsorbent is prepared from functionalized magnetic Fe3O4 nanoparticles as a carrier, sulfonated calix[6]arene obtained by pre-modifying calix[6]arene and trimesoyl chloride in an N, N-dimethylformamide solvent through a nucleophilic substitution reaction, wherein the adsorbent not only has an inherent large cavity structure of the calix[6]arene, but also has a cross-linked net structure. The adsorbent shows inherent superparamagnetism, large specific surface area, excellent stability and abundant binding sites, and shows excellent performance in separation, enrichment and energy gathering of target compounds.

Description

technical field [0001] The invention belongs to the technical field of supramolecular materials, and in particular relates to an adsorbent and its preparation method and application. Background technique [0002] Basket-like configurations and calix[n]arenes of different sizes can specifically recognize metal ions, dyes, gases and some organic micropollutants. As we all know, as the third generation of supramolecules following crown ethers and cyclodextrins, calix[n]arene is a macrocyclic compound with inherent porosity, which can be easily prepared by formaldehyde and p-tert-butylphenol. [0003] In order to improve the affinity of guest molecules, through simple chemical modification, calix[n]arene introduces active groups on the upper and lower edges, and combines with small molecules with specific structures and functional groups to prepare organic porous polymer networks to expand in front of samples. The range of applications in the processing medium. [0004] In rel...
