Developed micropores and large specific surface area activated carbon for water purification

Activated carbon for water purification Water purification activated carbon is generally columnar particles, with large specific surface area, developed micropores, high mechanical strength, fast adsorption speed, high purification degree, not easy to remove powder, and long service life. Water purification activated carbon can be widely used in chemical industry, electronic medicine, printing and dyeing, food and domestic water, industrial water solution filtration, adsorption, purification and impurity removal, and can also be used for deep purification of industrial wastewater. It can effectively remove harmful substances such as odorous chlorine, cyanide and various heavy metal ions and decolorize. After the adsorbate is transferred to the outer surface of the coconut shell activated carbon, only a very small part is adsorbed on the outer surface, and most of it continues to enter the micropores inside the coconut shell activated carbon. This process is called intrapore diffusion. The diffusion rate in the micropores depends on the mobility of the adsorbate in the micropores, which is related to the structural distribution of coconut shell activated carbon and the size and structure of the adsorbate molecules. The micropore diffusion rate is less affected by the concentration of the solution and the size of the outer surface area of the particles.
Adsorption Principle Using activated carbon filter adsorption method to purify water is to use its porous solid surface to adsorb and remove organic matter or toxic substances in the water, so that the water can be purified. 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, the stronger the hydrophilicity, and the worse the adsorption capacity of activated carbon on it. On the contrary, organic matter with small solubility, poor hydrophilicity and weak polarity, such as benzene compounds, phenolic compounds, etc., has stronger adsorption. ability.
Specific surface area of coconut shell water purification activated carbon The reason why water purification coconut shell activated carbon produces adsorption is because it has a developed pore structure, just like the sponge we have seen. Under the same weight conditions, the sponge is more Other objects can absorb more water, and the reason is also 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 inside into a plane, the area will reach square meters. The specific surface area of meters is/! Therefore, activated carbon with better effect is lighter in weight than the same volume. This is the reason. Welcome to call
