| titleOfInvention | A kind of adsorbent and its preparation method and application |
| abstract | The invention belongs to the technical field of adsorbent materials, and in particular relates to an adsorbent and a preparation method and application thereof. The invention provides a preparation method of an adsorbent, comprising the following steps: mixing cyclodextrin, 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetramethyl-1, 1'-spiral bis-indane, tetrafluoroterephthalonitrile, catalyst, water-carrying agent and solvent are mixed, and an addition reaction is carried out to obtain a primary adsorbent; after the primary adsorbent is mixed with a hydrochloric acid solution, washing is performed in turn , solid-liquid separation and drying to obtain the adsorbent. In the present invention, 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetramethyl-1,1'-spiral double indane has a twisted structure, which is beneficial to increase the adsorbent molecule Compared with activated carbon, cyclodextrin has a more precise cavity size, which can improve the selective recognition and adsorption selectivity of the adsorbent to the plasticizer in liquor. |
