Activated Carbon
Activated carbon is known as the universal adsorbent for good reason; due to it's extremely high surface area (that can range from 500-2000 m2 per gram), activated carbon can adsorb or catalyze and remove most organic and many inorganic compounds from both liquids and gases
No other material can come close to matching activated carbon as an adsorbent based upon its effectiveness, economics, versatility and ability to be recycled in many cases.
Adsorption is a surface phenomena, therefore the total surface area with respect to pore size and volume are the criteria in determining it's effectiveness in a particular application. Activated carbon can be manufactured from many carbonaceous starting materials such as wood, coal, coconut shell, peat, bone char, petroleum or rayon cloth.
It is the base material that determines how a pore structure will exist and the distribution of these pores are the key to understanding which type of carbon is best suited for a specific application. (A sponge full of "pinholes" can not adsorb "marble sized" constituents). The following chart list the more popular commercial grades available along with their varied characteristics:
Factors to consider when reviewing a carbon application include: pH, temperature, flow rate, contact time, solubility, compatibility, pressure drop, backwash, bed expansion, humidity (for gas streams), spent carbon removal, handling and disposal, and carbon particle size and type - powder, granule, pellet, bead, fiber and/or mesh size.
