Coconut shell granular activated carbon has a wide range of functions, purity and quality

Activated carbon for water purification
Activated carbon for water purification is generally columnar particles with large specific surface area, well-developed micropores and high mechanical strength
Principle of adsorption The use of activated carbon filter adsorption method to purify water is to use its porous solid surface adsorption Purify the water by removing organic matter or toxic substances from the water. Research shows that activated carbon has strong adsorption capacity for organic matter within the molecular weight range. The adsorption of organic matter by activated carbon is affected by its pore size distribution and organic matter characteristics, mainly by the polarity and molecular size of the organic matter. For organic matter of the same size, the greater the solubility and stronger hydrophilicity, the worse the adsorption capacity of activated carbon on it. On the contrary, it has strong adsorption capacity for organic matter with small solubility, poor hydrophilicity and weak polarity, such as benzene compounds and phenolic compounds.
Specific surface area of coconut shell activated carbon for water purification
The reason why coconut shell activated carbon for water purification produces adsorption is because it has a developed pore structure, just like the sponge we have seen. Under the same weight conditions, sponge The reason why it can absorb more water than other objects is because it has a developed pore structure. The degree of developed pores of activated carbon is unimaginable. If you take grams of activated carbon and unfold all the pore walls into a plane, the area will reach square meters (that is, The specific surface area is / ), so the activated carbon with better effect is lighter in weight than the same volume. This is the reason.
