The invention provides a method for preparing a porous composite membrane of imprinted polymer by using orange peel, belonging to the technical field of wastewater treatment. The method for preparing the porous composite membrane of the imprinted polymer by using the orange peel is characterized by comprising the following steps of: s1 preparation of orange peel cellulose: pulverizing pericarpium Citri Tangerinae to 100 mesh, removing flavone to obtain granular cellulose, soaking in 20% isopropanol for 1-3 hr, cleaning for 3-5 times, soaking in 0.1mol/L sodium hydroxide solution for 1-3 hr, and cleaning to neutrality; s2 grafting reaction; preparing S3 imprinted polymer; and (8) preparing the S4 porous composite membrane. The invention has the advantages that the orange peel cellulose is used as a framework, the target ions are used as a template, and the porous composite membrane of the imprinted polymer with high wastewater target ion adsorption is synthesized. |
