Powdered activated carbon adsorption powerful reason

Powdered activated carbon is made of needle charcoal with high quality wood chips and fruit shells as raw materials. Produced by zinc chloride method, it has developed mesoporous structure, large adsorption capacity, rapid filtration and other characteristics, then its strong adsorption function needs to be illustrated from these three aspects: Firstly, the pores of powdered activated carbon have an adsorption potential, relying on the gravitational force of carbon molecules and adsorbed molecules and the formation of a pore size, the smaller the pore size, the stronger the adsorption potential. Second, the molecular motion theory: all objects are composed of molecules or atoms, molecules (atoms) have gaps between them. Molecules (atoms) are in a never-ending thermal movement without rules, molecules collide with each other very frequently, in the standard state, the molecules have an interaction force, generally manifested as gravitational force. Third, the diameter of the collision molecules and powdered activated carbon pore diameter to match, when the molecular diameter is slightly smaller than the pore diameter, the molecules encountered after the hole is difficult to run out, that is, adsorbed. The number of adsorbed molecules is large, indicating that its adsorption capacity is stronger. Only the pore diameter...
