Activated charcoal is good at trapping other carbon-based impurities (“organic” chemicals), as well as things like chlorine. Activated carbon for water purification is a kind of activated carbon used for water purification. Purifying water by adsorption method of activated carbon filter material is to use its porous solid surface to adsorb and remove organic matter or toxic substances in water to purify water. Studies have shown that activated carbon has a strong adsorption capacity for organic matter with a molecular weight range of 500-1000.

It is mainly used for filling, dechlorination, oil reduction and purification of urban drinking water, pure water, distilled water, ultrapure water and other manufacturing equipment, as well as deep purification of various industrial wastewater.

The adsorption of organic matter by activated carbon is affected by its pore size distribution and the characteristics of organic matter, mainly by the polarity and molecular size of organic matter. For organic matter of the same size, the greater the solubility and the stronger the hydrophilicity, the worse the adsorption of activated carbon to it. On the contrary, it has a strong adsorption capacity for organic matter with low solubility, poor hydrophilicity and weak polarity, such as benzene compounds and phenolic compounds.
