Fuchsine Adsorption from Aqueous Solution by Epichlorohydrin Crosslinked Peanut Husk

Abstract:

The adsorption of fuchsine by peanut husk, which was crosslinked by epichlorohydrin was studied with variation in the parameters of contact time, pH, initial fuchsine concentration and temperature. They were used for equilibrium adsorption uptake studies with fuchsine. The results indicate that adsorption equilibrium could be well described by both the Langmuir and the Freundlich isotherm equation. The adsorption followed the pseudo-second order model. The thermodynamic constants of the adsorption process were also evaluated, which suggest an endothermic adsorption process which runs spontaneously.
