| titleOfInvention | Polysilicate aluminum cerium acrylate flocculant and preparation method and application thereof |
| abstract | The invention discloses a polysilicate aluminum cerium acrylate flocculant and a preparation method and application thereof, wherein tuff is ground and sieved to obtain tuff powder; respectively weighing aluminum ash and tuff powder, mixing, and stirring to obtain tuff mixed powder; respectively weighing water and tuff mixed powder, mixing, and stirring to obtain tuff; adding concentrated sulfuric acid into the mortar, uniformly stirring to make the pH of the slurry be 1-2, and aging for 3-6 hours to obtain silicon-aluminum polymerization slurry; adding acrylic acid into the silicon-aluminum polymerization slurry, uniformly stirring, and aging for 1-3 hours to obtain acrylic acid mixed silicon-aluminum polymerization slurry; weighing ammonium ceric nitrate and acrylic acid mixed silicon-aluminum polymer slurry, mixing, uniformly stirring, aging for 6-12 hours at the temperature of 20-80 ℃, drying in vacuum, grinding, and sieving with a 200-400-mesh sieve to obtain the polysilicon aluminum-cerium acrylate flocculant. The flocculant prepared by the invention can efficiently remove various heavy metal pollutants in water, and has the advantages of small dosage and high heavy metal removal rate. |
