Abstract :Metal contamination is one of the most serious global problems. This investigation deals with the use of Aksaray pumice for the adsorption of cobalt ions. The factors affecting the adsorption on Aksaray pumice were examined. Pumice activated at 873 K for two hours before contact with cobalt ions. UV-Vis spectrophotometer was used to measure cobalt ions concentrations. The response surface methodology was utilized to evolve the predictive model for adsorption of cobalt ions on Aksaray pumice. The experimental and predicted maximum removal efficiency of 40 % and 37 % was obtained, respectively. The results showed that Aksaray pumice can be used as adsorbent for cobalt ions.
