Abstract :

The treatment of dyes in industrial wastewaters poses several problems as dyes are generally stable to light and oxidation and hence they of aerobic digestion. Amongst the numerous techniques of pollutant removal, adsorption is an effective and useful process. Specifically when searching for natural raw materials as a possible source that could provide a successful low cost solution for adsorption. This study investigates the potential use of groundnut shells and coconut shells pretreated with concentrated acids, for removal of Congo red dye from synthetic solution through varying dye concentrati dosage, contact time and pH. The maximum color removal efficiencies of groundnut shell at a dosage of 120 mg/l for time duration of 120 min found to be up to 57% and for coconut shell at a dosage of 120 mg/l for time duration of 120 min found aqueous solution also it shows better outcomes in acidic nature. With this cheap and ecofriendly adsorbent considerable dye removal can be achieved. So, it can be substituted for expensive activated carbon. With the experimental data obtained in this study, it is possible to design and optimize an economical treatment process for the dye removal from industrial effluents.
