A chitosan-based hydrogel adsorbent capable of visually identifying and removing mercury ions and its preparation method and application |
| abstract |
The invention provides a chitosan-based hydrogel adsorbent capable of visually identifying and removing mercury ions, and a preparation method and application thereof. The preparation method of the present invention comprises the steps of: polyethylene glycol and 4-aldehyde benzoic acid are reacted to prepare benzaldehyde-terminated polyethylene glycol; rhodamine 6G hydrazide and benzaldehyde-terminated polyethylene glycol The polyethylene glycol-modified rhodamine 6G hydrazide was prepared by the reaction; the polyethylene glycol-modified rhodamine 6G hydrazide was covalently cross-linked to the shell using benzaldehyde-terminated polyethylene glycol as a cross-linking agent On the polysaccharide, an environmentally friendly and high biosafety hydrogel adsorbent was prepared. The hydrogel adsorbent of the present invention shows excellent adsorption selectivity and removal ability for mercury ions, and shows specific color changes, so it can be used for visual identification and efficient removal of mercury ions in aqueous solutions; in addition, because the adsorbent is in a block shape , easy to remove after adsorption, and easy to operate in practical applications. |
