Abstract

Abstract Coconut shell activated carbon was impregnated with 2.08, 3.01, 6.41, 8.24 and 9.39% (w/w) copper. Mercury porosimetry was used to analyse pores ranging between 50 and 75,000 Å. Benzene adsorption isotherm and the Kelvin equation were used to analyse pores of radii 15–50 Å. Pores below 15 Å radius (micropore region) were analysed employing Kadlec's method and the Dubinin-Astakhov equation. Impregnants affect micro and transitional pores reducing the pore volume but without altering the basic structure.
