Abstract—The biosorbent α-keratin-alginate (KA) was
prepared by using the encapsulation technique in CaCl2 2 %
(w/v) solution. The biosorbent was characterized by Fourier
Transform Infrared (FTIR) and Scanning Electron Microscope
(SEM). The extent of adsorption was found to be a function of
the composition of α-keratin and alginate, the pH of solution
and contact time. The optimum adsorption of Fe ions in
aqueous solution was found at the composition of α-keratin and
alginate of 1:2 (w/w), the pH at 7.0 and contact time at 60
minutes. The adsorption of Fe ions on KA biosorbent was
comparatively higher than α-keratin and alginate only. The
adsorption capacity of KA biosorbent has the maximum
adsorption capacity of 658.4 mg/g while biosorbent α-keratin
and alginate are 464.7 mg/g and 528.1 mg/g, respectively.
Adsorption of Fe ions in aqueous solution followed the
Freundlich adsorption isotherm, and the dynamic adsorption
model could be described through a pseudo-second order
kinetics.
