English Abstract

Zinc removal from simulated wastewater was achieved using cement kiln dust an adsorbent material.

Effects of contact time, pH, zinc ion concentration, rotational speed, and amount of CKD were investigated.

The best operating conditions were determined via application of response surface methodology.

Results showed that zinc concentration has the main effect on zinc removal efficiency followed by time, shaking, CKD dosage and pH.

The best operating conditions were found to be pH value equal to 8, contact time of 90 minutes, rotational speed of 300 rpm, zinc ion concentration of 20 ppm and the amount of cement kiln dust (CKD) equal to 35 g L.

based on these optimum condition, 99.37% zinc removal efficiency was obtained
