Abstract

Activated carbon has been produced from waste tyres using chemical treatment. The effects of activation chemical used, chemical ratio, soaking time in the impregnation step, activation temperature and time duration of the activation step were investigated. Surface area, pore size distribution, total pore volume, adsorption capacities of acid dyes (AY117 AB25) were determined. The carbon product with the highest adsorption capacity, q_e = 0.178 mmol dye/g carbon for AY117 and q_e = 0.257 mmol dye/g carbon for AB25 was produced using KOH in chemical ratio 6 : 1 for 2 h of soaking and activated at 750°C for 3 h, having surface area 302.9 m²/g.
