Coconut shell activated carbon for water purification manufacturers offer coconut shell granular activated carbon

Activated carbon for water purification
Activated carbon for water purification is generally columnar particles with large specific surface area, developed micropores and high mechanical strength.
Adsorption principle: Purifying water with activated carbon filter material adsorption method is to use its The porous solid surface adsorbs and removes organic matter or toxic substances in the water to purify 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 the characteristics of the organic matter, mainly by the polarity and molecular size of the organic matter. For organic matter of the same size, the greater the solubility and the stronger the hydrophilicity, the worse the adsorption capacity of activated carbon to it. On the contrary, the organic matter with small solubility, poor hydrophilicity and weak polarity, such as benzene compounds and phenolic compounds, has a relatively good adsorption capacity. Strong adsorption capacity.
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 conditions of the same weight Below, a sponge can absorb more water than other objects. The reason is also because it has a developed pore structure. The degree of developed pores of activated carbon is unimaginable. If you take a gram of activated carbon and unfold all the pore walls inside into a plane, this The area will reach square meters (that is, the specific surface area is/)! Therefore, activated carbon with better effect is lighter in weight than the same volume. This is the reason.
