The purpose of this study is preparation and characterization of activated carbon using wood apple rind waste biomass by using two different acids like sulphuric acid and phosphoric acid. A series of experiments were conducted in a batch mode system to evaluate the capacity of the adsorbent by changing the variables .i.e. initial pH, initial dye concentration and contact time. The FT-IR analysis of the activated carbon depicts the presence of various functional groups present on it. The isotherm data were fitted with Langmuir and Freundlich models. The kinetic data were fitted with pseudo first order and pseudo second order kinetic models. The pH of the dye solution plays a major role in the adsorption process and it is the most important factor compared to all other factors that affect the adsorption process.
