ASSESSMENT OF THE EFFICIENCY OF CRUSHED CERAMICS IN ADSORBING METHYL ORANGE DYE FROM WASTEWATER

Description

The potential of crushed, pulverized ceramics as a low-cost adsorbent for the removal of methyl orange from wastewater was investigated in this study. The influences of pH, contact time, initial metal concentration, adsorbent dosage and temperature were studied in batch experiments at room temperature. Maximum sorption for methyl orange was found to be at pH 2. The adsorption was rapid at the first 90 minutes of contact, with uptake of more than 90%, and equilibrium was achieved in 60 minutes of agitation. Langmuir, Freundlich, and BET isotherm models were applied to describe the adsorption of methyl orange dye. Freundlich model fitted the equilibrium data better, while the pseudo-second order kinetic model was the most fitting. It can be concluded that crushed ceramics can be considered as an alternative sorbent for the removal of the dye since it is effective, low cost, and abundant and can be obtained locally. The results showed that pulverized ceramics have the potential to be applied as alternative low-cost sorbent in the remediation of color contamination in waste water and it is therefore recommended.
