Colour Removal from a Simulated Methyl Red Wastewater by Adsorption on Carbon in a Fixed Bed

Authors : B.O. Isiuku, M. Horsfall and A.I. Spiff

Abstract: The aim of this research was to evaluate H3PO4-activated carbon from cassava peels waste in removing methyl red from aqueous solution (simulated wastewater) by adsorption in a fixed-bed column. Effects of influent concentration, adsorbent bed height and solution flow rate were studied. Experimental results were applied to Thomas and Yoon-Nelson Models. The adsorption capacity, rate constant, correlation coefficient associated with each model were calculated and mentioned. The maximum experimental adsorption capacity of 133.63 mg g-1 was obtained with influent concentration of 200 mg L-1, bed height 20 cm and flow rate 13.3 mL min-1. Adsorption capacity, qo, increased with increase in influent concentration, increase in bed height and decrease in flow rate. Maximum adsorption capacity related to the Thomas and Yoon-Nelson Models were 24.341 and 260.042 mg g-1, respectively at influent concentration 200 mg L-1, bed height 20 cm and flow rate of 13.3 mL min-1. Correlation coefficients show that the results fitted well into the Thomas and Yoon-Nelson Models.
