Utilisation of Cationic Surfactant Modified Kaffir Lime Leaves Residue for the Removal of Reactive Orange 16 Dye from Aqueous Solution: A Fixed-Bed Column Study

Abstract

The removal of reactive orange 16 (RO16) dye using residue as a non-conventional low-cost adsorbent will be studied. Column adsorption will be used to demonstrate how parameters such as adsorbent bed height and intake dye flow rate affect the results. The adsorption data were fitted to the Yoon-Nelson model for predicting breakthrough curves and timings. The time necessary for a breakthrough in Yoon-Nelson model will be set at 50% of the effluent RO16 to feed concentration. The correlation coefficients, R², for all two parameters will be used to determine the efficacy of the adsorbent in extracting RO16 from aqueous solution.
