| titleOfInvention | Preparation method and application of polyelectrolyte coating nanofiltration composite membrane for treating electroplating wastewater |
| abstract | The invention provides a preparation method of a nanofiltration composite membrane, which comprises the following steps of firstly mixing polyacrylonitrile and a first solvent to obtain an intermediate membrane liquid, and then coating the intermediate membrane liquid on a base membrane to obtain a carrier compounded with the intermediate membrane; then mixing polyethyleneimine, poly (methacrylic acid-2-hydroxy lactone), vinylpyrrolidone and a second solvent again to obtain a cross-linked composite membrane liquid, coating the cross-linked composite membrane liquid on an intermediate membrane of the carrier obtained in the step, and solidifying after electron beam irradiation cross-linking to obtain a nanofiltration membrane carrier; and finally, soaking the nanofiltration membrane carrier obtained in the step into a poly (4-styrenesulfonic acid) ammonium salt solution, taking out the nanofiltration membrane carrier, soaking the nanofiltration membrane carrier into a poly (dimethyldiallylammonium chloride) solution again, and then crosslinking the nanofiltration membrane carrier again through electron beam illumination to obtain the nanofiltration composite membrane. |
