This investigation deals with the use of cement kiln dusts waste (CKD) as adsorbent for removal two kind of acid dyes from simulated wastewater. cement kiln dusts waste prepared by dried at 60C°. The effect of pH: 2-12, contact time: 20- 180 min, sorbent weight: 0.5- 4.0 g were considered. The optimal pH value for acid dyes adsorption was found to be 2.5 for acid red dyes(ARD)and 6.5 for acid blue dyes (ABD). The equilibrium data were analyzed using Langmuir and Freundlich isotherm models. Freundlich model was found to fit the equilibrium data very well with high-correlation coefficient (R2). The adsorption kinetics was found to follow pseudo-second-order rate kinetic model, with a good correlation (R2 > 0.95 and 0.94) for acid red dyes(ARD) and acid blue dyes (ABD). respectively. The results showed that the cement kiln dusts waste was found to be an attractive low cost adsorbent for the treatment of wastewater.
