Organic cationic polyacrylonitrile flocculant and preparation method thereof |
| abstract |
The invention discloses an organic cationic polyacrylonitrile flocculant, which is a polymer formed by reacting polyacrylonitrile powder and dicyandiamide-formaldehyde polymer, and solves the problem of poor treatment effect of the flocculant on water-soluble dye and dye wastewater which is not easy to form colloidal particles in the prior art. |
