Question the quality of the activated carbon. Activated carbon, also referred to as activated charcoal, is an amorphous form of carbon. Activated carbon is an example of an absorbant. Keywords: Adsorption, Activated Carbon, Kinetics, Isotherm, Saw dust, Equilibrium. Techniques for removal of colour from waste water include biological treatment, coagulation, floatation, oxidation, hyperfiltration and adsorption. Activated carbon can vary greatly depending on the methods used to produce it. The difference is that in absorption, the substance being absorbed diffuses into the material, while in adsorption, the substance merely interacts with the surface of the material. For instance, the surface area available to adsorb pollutants can vary between 400 sq. However, activated carbon has substantial bulk material that cannot be utilized for adsorption. Thiol groups of adsorbent surfaces offer strong affinities for heavy metal ions, such as Hg(II), Pb(II), Cd(II), and so on. Activated carbon, also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. Activated carbon as an adsorbent is widely used because of its high adsorption abilities for a large number of chemicals [16-18]. Let's take a look at the science of activated carbon as a medium for adsorbing various types of chemicals and odors.
