Adsorption of Cationic Polyacrylamide Coal Washing Wastewater

Cationic polyacrylamide copolymerization has two groups that combine and adsorb with the surface of coal washing wastewater. One is the electrostatic physical adsorption between the quaternary salt cationic group and the negatively charged area on the coal surface, and the other is the amine group and the surface of coal particles. elements such as hydrogen bond adsorption. During the stirring process, when the coal particles collide with the agent, the cationic polar groups and amido groups in the colloid rapidly absorb, permeate, and diffuse on the surface of the coal particles, and cover the entire coal particle surface in the form of a film to remove coal particles. The structured hydration film and free hydration film on the surface of coal particles are beneficial to remove the attached water on the surface of coal particles and the bound water between particles. Suodi chemical Cationic polyacrylamide has a strong adsorption on the coal surface.
