| titleOfInvention | Multifunctional composite adsorbent, and preparation method and application thereof |
| abstract | The invention discloses a multifunctional composite adsorbent. Cross-linked chitosan is used as a matrix and is formed by cross-linking heavy metal ion imprinting chitosan by using a cross-linking agent; the cross-linked chitosan matrix is filled with nano Fe3O4 and nano TiO2; and the surface of the multifunctional composite adsorbent is modified by thiocarbamide so as to form a large amount of free amino groups. The invention correspondingly discloses a preparation method for the multifunctional composite adsorbent. The preparation method comprises the following steps of: performing photocatalysis loading, performing heavy metal ion imprinting to ensure the metal imprinting ions are fully reacted with chitosan in the heavy metal imprinting ions to form complexes, and adding the cross-linking agent and reacting; and adding epichlorohydrin and an acetone solution containing thiocarbamide, and modifying and grafting, finally oscillating and desorbing, and regenerating by using an alkaline solution to prepare the multifunctional composite adsorbent. By using the multifunctional composite adsorbent, heavy metal can be selectively separated and/or organic pollutants can be degraded. |
