Shell activated carbon | husk carbon price | shell activated carbon Iodine value |! Shell activated carbon activated carbon shell parameters is high quality fruit shell as raw material, drying, charring and high temperature steam activation refined processing of high-performance activated carbon adsorption . Look for black amorphous particles, developed pore structure, large surface area, strong adsorption capacity, high mechanical strength, bed resistance, good chemical stability, easy regeneration, durability, etc., and have a variety of particle size . Shell activated carbon use: shell activated carbon is widely used in deep purification drinking water, industrial water and wastewater; various gas separation, purification, purification; organic solvent recovery; industrial sugar, monosodium glutamate, medicine, liquor, beverages refining of precious metals;; decolorization, deodorization, refining chemical industry catalyst and catalyst carrier. Shell activated carbon activated carbon treatment of wastewater containing chromium. Chrome plating in a larger amount of a metal material, hexavalent chromium in the waste water with pH values ??were different in different forms. Activated carbon has a very well-developed porous structure and high specific surface area, with a strong physical adsorption capacity, can effectively absorb wastewater Cr (Ⅵ). The presence of a large number of the surface of activated carbon-containing groups such as hydroxyl (-OH ), carboxyl (-COOH), etc., they have electrostatic adsorption function of Cr (Ⅵ) chemical adsorption. Can be used in electroplating wastewater Cr (Ⅵ), water adsorption can meet the national emission standards. Tests showed that: the solution Cr (Ⅵ) concentration of 50mg / L, pH = 3, when the adsorption time 1.5h, adsorption properties of activated carbon and Cr (Ⅵ) removal are the best results. Therefore, the use of chromium-containing wastewater treatment process of activated carbon is the result of the combined effect of activated carbon in solution Cr (Ⅵ) physical adsorption, chemisorption, chemical reduction, etc..
