Surface area of granular activated carbon
WebOct 1, 2024 · The surface area of an activated carbon is practically not altered by the average particle size of the carbon. But while this size is smaller, the pores of the carbon are shortened, and the access routes to them increase. This substantially increases the adsorption kinetics. Factors related to adsorbate that require retention WebGranular activated carbon is defined as the activated carbon being retained on a 50-mesh sieve. Calgon Carbon produces GACs with a variety of materials, methods and degrees of activation to produce activated …
