Complete Guide to Activated Carbon Activated carbon is a common product used to filter and purify numerous substances. Although few people realize it, activated carbon touches everyone's lives. If you drink municipal water, use soap, brush with toothpaste, or drink decaffeinated coffee, your life involves activated carbon. Air purification is an important use for activated carbon as well.

Particle Size Distribution. Particle size distribution is another key factor in choosing an activated carbon for gold recovery, as it is largely linked to adsorption rate.³. Often, the unique requirements of the specific application at hand will require a balance of these characteristics to achieve the best results.

Granular activated carbon – activated carbon in particle sizes predominantly greater than 80 mesh. Hardness – a generic term referring to the resistance of a particle to breakdown as measured by specific tests. Heat of adsorption – the heat evolved during adsorption.

The Elvoich equation, a liquid film diffusion and an intra-particle diffusion model were used to fit the kinetic data. The results indicate that the adsorption of K + onto activated carbon is influenced by many factors including pore size distribution, specific surface area and the surface chemistry of the activated carbons. The Temkin equation ...

Granular activated carbon has a relatively larger particle size compared to powdered activated carbon and consequently, presents a smaller surface. Diffusion of the adsorbate is thus an important factor. These carbons are therefore preferred for all adsorption …
