Sažetak:
Several adsorbent such as natural zeolite clinoptilolite, modified zeolite, grape and olive wastes have been investigated for removing chromium (VI) ions from aqueous solutions by performing batch kinetic sorption experiments. Natural zeolite, modified zeolite, grape and olive wastes have removed 5 %, 13 %, 73 % and 62 %, respectively, of Cr (VI) ions from aqueous solution. Equilibrium experimental results were fitted to Langmuir and Freundlich isotherms to obtain the characteristic parameters of each model. According to an evaluation using Langmuir equation, the maximum Cr (VI) adsorption capacity of grape waste was 108.12 mg g-1 and of olive waste 100.47 mg g-1 at pH 2. The equilibrium kinetic data were analyzed using pseudo-first and second-order models and parameters were estimated by using non-linear regression analysis. The adsorption of Cr (VI) ions increased with increasing temperature indicating spontaneous and endothermic nature of the adsorption process.
