AB  - The kinetics of chromium ions sorption from aqueous solution on fungi biomass have been
investigated in a batch system. The experimental data were analysed based on an intraparticle diffusion
equation and a pseudo-second-order mechanism, in order to predict the constant rate of sorption and
the equilibrium capacity with the effect of initial chromium ions concentration, temperature and initial
solution pH. The results indicate that the sorption mechanism is described by a pseudo-second order
equation. Intraparticule diffusion was signifiant in the lower concentration systems. The sorption of
chromium onto the biomass fungi sorbent is favoured at higher concentrations of chromium solution,
low temperatures. An activation energy of sorption was evaluted as 11.7 Kj.mol-1 for the sorption of
chromium ions on fungi biomass. The results show that the sorption of the chromium ions on fungi
biomass is exothermic nature process.
