| dc.description.abstract | Modified chicken feather has a potential to become biosorbent for removal of lead (II) ions in aqueous solutions. The chicken feathers were pre-treated using alkali and acid solutions at 1M concentration. Alkaline treated chicken feathers have resulted the best biosorption performance among others. The effects of pH, biosorbent dosage, concentration of heavy metal solution and contact time were studied to find the optimum condition for biosorption. Optimum adsorption was observed at pH 5, biosorbent dosage of 1.5g, 50 ppm of initial heavy metal solution concentration and 60 min of contact time. Under the optimum conditions, the highest % removal recorded was 93.5%. Results showed that equilibrium data were best described by the Langmuir isotherm with R2 value of 0.9808, which means monolayer of heavy metal ions stickled on the biosorbent surface. Maximum adsorption capacity was 7.28 mg/g from Langmuir. The adsorption kinetics followed the pseudo-second order, and this indicates that the alkaline treated chicken feathers used in this study undergone the strong chemisorption process with the lead (II) ions. For characterization of alkaline treated chicken feathers, the functional group observed to have changes in intensity were C-Cl group, C-O group, C-H group and C-OH. From this study, C-Cl, C-O and C-OH functional group have disappeared while C-H functional group has appeared, indicates that adsorption process was occurred mostly at this functional group. | en_US |
