Abstract

Adsorption of Fe(III) on the biosorbent from polymerization of nephelium fruit peel extract with aldehyde was carried out under acidic conditions (pH=5). The adsorption process was carried out to determine adsorption equilibrium, kinetics study, capacity (qe) and adsorption constants of Fe(III) adsorption on the biosorbent. The adsorption equilibrium was obtained after 10 minutes of the adsorption process. The kinetic model of Fe(III) adsorption at the pH solution condition pH=5 followed the kinetics model from Ho which is pseudo-second order with the qe value of 40.65 mg.g−1 and the adsorption rate constant (h) of 3.33 × 103 mg.g−1.min−1.
