| titleOfInvention | Method for preparing lignin-based heavy metal ion adsorption material through sulfydryl-alkenyl click reaction |
| abstract | The invention discloses a method for preparing a lignin-based heavy metal ion adsorption material by using a sulfydryl-alkenyl click reaction. Firstly, lignin reacts with alkenyl compounds to prepare alkenyl lignin, and then the alkenyl lignin reacts with mercapto compounds rich in nitrogen and oxygen atoms through mercapto-alkenyl click reaction under the condition of ultraviolet illumination/heating to prepare the lignin-based heavy metal ion adsorbing material. The preparation process has mild reaction conditions and high reaction efficiency, and the prepared lignin-based heavy metal ion adsorption material contains more amino, thioether, carboxyl and other heavy metal adsorption sites and can be used for adsorbing Pb in water 2+ 、Hg 2+ 、Cu 2+ The heavy metal ions have the advantages of high adsorption capacity, good adsorption selectivity, recyclability and the like. |
