Abstract
Buffing dust generated from leather industry can be considered as a so urce for obtaining activated carbon for the removal of dyes from waste water. The adsorption capacity of buffing dust based activated carbon was 6.24 mg/g at a pH 3.5, temperature 30 degrees C for dye concentrat ion of 125 mg/L and carbonisation temperature 900 degrees C. Effect of initial dye concentration, pH, temperature and particle size on dye a dsorption and pore diffusion were also determined. The enthalpy of ads orption was determined to be - 15.69 kJ/mol.
