A STUDY ON REMOVING HEAVY METALS FROM WASTEWATER BY USING LOW-COST ADSORBENTS
The purpose of this study was to investigate the possibility of the utilization of rice straw, bagasse, maize cob, garlic skin, and onion skin as a low cost adsorbents. Batch experiments were carried out on a laboratory scale to evaluate the adsorption efficiency and removal of heavy metals from aqueous solutions by different natural waste materials under various conditions of pH, contact time, and initial metal ion concentration. The equilibrium time was found to be 120 min. and optimum pH value was found to be 6.0. To apply the finding of the study, real wastewater sample was obtained and different adsorbents were used for its treatment as a case study. The investigated adsorbents showed a good efficiency in removing toxic heavy metals such as lead, cadmium, arsenic, chromium and copper from their aqueous solutions.
