AB - 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.
