Complete modeling of cadmium removal on Tharcoal which is lignite in its nature has been carried out. A Design of Experiment (DoE) approach has been used for simultaneous optimization ofdifferent sorption parameters. DoE showed the positive effect of agitation time on removal of cadmium and negative effect of pH, interaction term pH and amount also showed a negative effect on removal. Values of sorption capacity calculated at optimum parameters for Langmuir, Freundlich and D-R isotherm were 100 mgg-1, 47.86mgg-1and 8.422mgg-1respectively. Amongall tested kinetic models second order rate equation showed a best fit
