Sorption of Cu (II) Ions on Orange Peel
An adsorption process is the most effective technique and used for the elimination or reduction of metal ions from wastewater. However, the process is not economical since the activated carbon used as a sorbent is costlier. Hence investigators are inspecting to identify cost-effective, efficient, locally available adsorbent materials. In this research work, attempts have been made to check the efficiency of powdered orange peel (POP) with powdered activated carbon (PAC) in removing Cu2+ ions from the aqueous solution. Experiments have been carried out using the batch mode method. In this removal process, the influence of various physico-chemical parameters, like pH, contact time, adsorbent dose, Cu2+ ions awareness and adsorbent particle size at the adsorption of Cu2+ ions through each POP and PAC were investigated. Results found out that the 69.75% elimination of Cu2+ ions was determined with powdered orange peel at pH 5, contact time 60 min, adsorbent dose 3.5 g/L and Cu2+ ions concentration of 200 ppm. Whereas, the powdered activated carbon has shown elimination of 77.4% at pH 5, contact time of 45 min, adsorbent dose 2.0 g/L and Cu2+ ions concentration of 500 ppm. Equilibrium records had been analyzed using the Langmuir, Freundlich model.
