EQUILIBRIUM AND KINETICS STUDY OF CRYSTAL VIOLET DYE REMOVAL BY USING LOW COST WATER HYACINTH ROOT POWDER

J. S. YADAV, M. SONI AND L. S. THAKUR

Abstract

Adsorption of crystal violet (CV) dye on water hyacinth root powder (WHRP) has been investigated as a function of solution pH, adsorbent dose, initial concentration and treatment time in batch reactor. A low cost natural adsorbent WHRP was used for the removal of CV. The optimized parameters were found to be pH: 7, adsorbent dose: 10 g/L, initial concentration: 20 mg/L, and treatment time: 160 min. At these optimum conditions 90% removal of CV was observed. The maximum adsorption capacity of CV was found to be 8.40 mg/g. Freundlich isotherm suitably fitted to equilibrium data. Adsorption kinetic facts are satisfactorily represented by the pseudo-second order kinetic model. The results of experimental study showed that WHRP an outstanding adsorbent for the removal of CV from wastewater.
