Ammonia adsorption on chemically modified activated carbon cloth

Abstract

The effect of CuCl2, CuSO4, and H2SO4 impregnation of activated carbon cloth on ammonia adsorption at 303 K were examined. Cellulose based activated carbon cloth of various activities were used as the starting materials. The carbon cloth surface area and porous structure parameters were determined by N-2 adsorption at 77 K using the gravimetric McBain method. Ammonia adsorption was significantly increased on impregnated samples, at low relative pressure (low NH3 concentration). Ammonia adsorption at high concentration was found to be directly influenced by the available micropore valume of the activated carbon cloth.
