Abstract

The effect of adsorption parameters such as pH, initial concentration, adsorbent dose and contact time, and adsorption kinetics and isotherm of Fuchsine basic (FB) dye removal by acid activated kola nut pod carbon (KPAC) and base activated kola nut pod carbon (KPBC) was observed in this study. Pseudo-first order model and pseudo-second order model was the selected kinetics model. Result obtained suggested that the pseudo-second order model fitted the adsorption data than the pseudo-first order model, as gathered from their regression coefficients (R2) and rate constants (K). Langmuir isotherm model and Freundlich isotherm model were used in fitting the experimental data, and the regression coefficients (R2) of Langmuir isotherm shows that it better described the adsorption isotherm of FB dye adsorption using the produced activated carbons than the Freundlich isotherm model. Experimental result also showed that the adsorption of FB dye using KPAC and KPBC is dependent on pH, initial concentration, adsorbent dose and contact time. Kola nut pod is a good precursor for producing cheap and highly efficient activated carbon.
