Abstract

This work investigated the potential use of activated carbon produced from saccharum officinarum waste as an adsorbent for the removal of dye stuff from aqueous solution. The activated carbon was impregnated using Orth-phosphoric acid for chemical activation. Some physicochemical parameters of the activated carbon studied include, pH, bulk density, ash and moisture content. Adsorption experiments were conducted at varying contact times, initial dye concentration and temperature. Adsorption equilibrium was achieved in less than 40 minutes of contact time. Adsorption of dyes increased with increasing temperature. Thermodynamic characteristics which include free energy, enthalpy and entropy values were assessed using van’t Hoff equation. Negative free energy and positive enthalpy values indicate the feasibility as well as endothermic nature of the adsorption event. Positive entropy suggests increased disorderliness at the solid/solution interface during adsorption process. The kinetic study shows that pseudo-second-order model is best fit for the experimental data obtained
