Microcrystalline Cellulose from Groundnut Shell as Potential Adsorbent of Crystal Violet and Methylene Blue. Kinetics, Isotherms and Thermodynamics Studies

The isolation of microcrystalline cellulose from a groundnut shell is reported. Adsorption experiments were carried out for the removal of cationic crystal violet and methylene blue and it follows Langmuir model. Positive enthalpy and negative free energy changes have shown endothermic and favorable processes. The results reflect good adsorption process.
