Abstract

This study reported the accumulation of Methylene Blue (MB) by sulphonated Solanum virginianum carbon (SSVC) using batch technique. Adsorption studies are conducted in altered initial dye concentrations, adsorbent doses, pH, contact
time and temperature. The removal of MB increases with decrease in concentration of dye. The experimental data was
analysed by Langmuir, Freundlich and Temkin models. The adsorption capacity (Qo ) of SSVC was found to be 24.12 mg/g. The process of dye accumulation follows second order kinetics. From the effect of temperature, thermodynamic parameters such as the free energy change (∆G°), enthalpy change (∆H°) and entropy change (∆S°) were determined.
