Rhodamine 6G, a cationic dye is used to dyeing silk, cotton, wool, baste fiber, paper, leather, and plastic. It is toxic and carcinogenic in nature. Hence it is essential to remove Rhodamine 6G from dyeing industrial discharge and contaminated drinking water resources. In this present work, a waste plant material Prosopis spicigera L.wood is carbonised (by natural process) and its composite with iron oxide, is used for the removal of Rhodamine 6G from aqueous solutions by batch and column methods. The PSLW carbon-iron oxide compositeis characterized by FTIR for functional group, scanning electron microscope for surface morphology and potentiometric titration for pHzpc. Batch experiments have been carried out to investigate the influence of sorption parameters such as initial dye concentration, pH, contact time, in the presence of other ions and temperature on the removal of Rhodamine 6G. The batch experiments were carried out at pH 6.0. The adsorption equilibrium fits Langmuir isotherm. The kinetic data follows pseudo second order model. The thermodynamic study indicated that the adsorption of dye is spontaneous and endothermic in nature. In order to apply this process to industrial and domestic applications, column analysis was performed. Column data was analysed using Thomas model.
