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.
