Abstract:
Chitosan and silica were used as adsorbents for the removal of humic acid in batch
process. The point of zero charge of chitosan and silica were pH 8.8 and 8.6, respectively. The
experimental results showed that adsorption capacity onto 0.2 g of chitosan and silica as
adsorbents for humic acid solution at the concentration of 13.5 mg/L were 1.3 and 2.6 mg/g,
respectively. The pseudo-first order and pseudo-second order were employed to determine the
adsorption kinetics. It was found that the kinetics of adsorption could be elucidated by pseudosecond
order. The initial rate of adsorption and the half-adsorption time were 0.5 mg/g-min and
2.1 minutes for chitosan, and 4.7 mg/g-min and 0.6 minutes for silica, respectively. The
transport processes of humic acid from bulk solution to be adsorbed at the surface of adsorbents
occurred in 2 steps. The film diffusion was rate limiting step of both adsorbents.
