What is the principle of activated carbon adsorption

Purifying water with activated carbon filter material adsorption method is to use its porous solid surface, adsorption removal of organic matter or toxic substances in the water, so that the water is purified.The research shows that the activated carbon has a strong adsorption capacity for organic matter with molecular weight in the range of 500-1000.The adsorption of activated carbon on organic matter is affected by its pore size distribution and the characteristics of organic matter, mainly by the polarity and molecular size of organic matter.The same size of organic matter, the greater the solubility, the stronger the hydrophilicity, activated carbon on its adsorption of the worse, on the contrary, the solubility of small, poor hydrophilicity, weak polarity of organic matter such as benzene compounds, phenolic compounds have strong adsorption capacity.Water purification activated carbon is generally used for water purification, removal of odor odor, removal of heavy metals and colonies in the water, improve the quality of water, tap water, pure water, high pure water treatment of the ideal material.It can also be used for deep purification of sewage.
