AB - CTC grade, 12×30 BSS particle size and 104 m2/g surface area, was impregnated with metal salts such Cu, Cr, Ag, Mo andZn, and an organic compound Triethylene diamine (TEDA) to prepare different carbon systems such as whetlerite, whetlerite/TEDA, whetlerite/KI/KOH and ASZMT. The prepared adsorbents along with active carbon were characterized for surfacearea and pore volume by N2 adsorption at liquid nitrogen temperature. These carbon systems were compared for their CT(concentration X time) values at 12.73 to 53.05 cm/sec space velocities and 2 to 5 cm carbon column bed heights. The carbon3.712 mg/L iodine vapour concentration and 12.73 cm/sec space velocity. The study clearly indicated the adsorption capacitiesof carbon systems to be directly proportional to their surface area values. Dead layer with all the prepared carbon systems wasfound to be less than 2.0 cm indicating it to be minimum bed height to have protection against I2 vapours. Effect of carbon bedheight and flow rate was also studied. The active carbon showed maximum protection at all bed heights and flow rates incomparison to all other impregnated carbon systems, showing that only physical adsorption is responsible for the removal ofiodine vapours.
KW - 1. IntroductionActive carbon of high surface area has been widely usedfor the purification of the air and water using the adsorptioncapacity of this universal adsorbent [1-3]. Active carbonremoves the wide range of chemicals based on physisor-ption;
