M. Tech. Chemical Engineering. / Discusses the objectives of the research project are to: 1. Develop a cost effective technique for modifying the surface groups of ACs with a view to induce selectivity properties towards PGMs. 2. Characterize the chemically treated ACs. 3. Determine adsorption capacities and selectivity of Amine treated ACs by performing batch adsorption tests. 3. Investigate the adsorption of Pt (IV) in a Continuous stirred tank reactor. The data generated according to the project objectives will assist in obtaining the following informations. 1. Adsorption isotherms - Find the maximum adsorption capacity of ACs for different solution concentrations, and temperature. Determine the effect of base metals on adsorption and hence extend the adsorption isotherm equation from single component to a multi-component adsorption isotherm. 2. Kinetics data - Determine the rate of change of metals in solution with time at various initial concentration, temperature and acid strength. 3. Characterization of modified ACs - Determine surfaces morphology of ACs using SEM-EDS.
