Abstract

Modified Ceiba pentandra sawdust has been investigated as an adsorbent for the removal of methyl violet from aqueous solutions. Batch experiments were carried out to investigate the effect of pH, contact time and methyl violet concentration on sorption efficiency. The favourable pH for maximum methyl violet adsorption was 5. For the investigated methyl violet concentration (0-100 mg/L), maximum adsorption rates were achieved almost in 10-20 min of contact. The experimental data fitted well with the Freundlich isotherm while the kinetics of methyl violet adsorption was well described by the pseudo-second order kinetic model.
