| titleOfInvention | Two-dimensional layered water-stable dye adsorbent and preparation method thereof |
| abstract | The invention provides a two-dimensional layered water-stable dye adsorbent and a preparation method thereof. Using the organic ligand 2, 3-bis (4-amino-3-methylbenzoic acid) -1, 4-quinoxaline (H) 2 QDAB). The chemical formula of the obtained compound is [ Zn (QDAB) (H) 2 O)]·2H 2 O, accurately weighing the organic ligand H under the conditions of solvent heat temperature and solvent temperature 2 QDAB and Zn (NO) 3 ) 2 ·6H 2 And carrying out thermal reaction on O in a mixed solution of DMF and water under the condition of adding NaOH to obtain the organic-metal framework crystal. The metal-organic framework material has better water stability, has better adsorption effect on two dyes of organic dye molecules, namely methyl blue and crystal violet, has weaker adsorption capacity on rhodamine B and methyl orange, shows a certain selective adsorption effect, and can be used for removing the organic dye molecules. In addition, due to the unique structural characteristics, the method is expected to be applied to gas adsorption separation. |
