Among these methods, adsorption using activated carbon is a key technique that improves VOC adsorption, with increases in use being due to its low cost, hydrophobic properties, high surface area, and the microporosity of activated carbon which provides an excellent VOC adsorption capacity. And activated carbon, an adsorbent with its large porous surface area, controllable pore structure, thermo-stability and low acid/base reactivity. Is currently receiving great attention, owning to its superior and efficient ability in air pollution control.
