The adsorption behaviour of Basic Red-12 on Vermiculite and has been investigated to understand the physicochemical process involved and to explore the potential use of low cost materials in textile effluent treatment and management. The adsorption process was found to be pH dependent and optimum pH obtained is 8.0. The equilibrium was established in 2 h. The process obeys Langmuir and Freundlich model. Scanning electron microscopic analysis reveals a conspicuous surface morphology of VC. The results of XRD and FTIR spectroscopy reveal that the process is electrostatic complexation mechanism driven.. The thermo dynamical measurements suggest that all processes are exothermic accompanied with negative ΔGo, ΔHo and ΔS o.
