In dyes were obtained mostly from inorganic sources and some very expensive organic dyes were obtained from natural sources. These dyes are highly toxic when they disposed in to environment without any treatment. In this work, carbonized Lawsonia sp. were used as an adsorbent for reducing the colour of malachite green dye with various pH such as 5, 6, 7, 8, 9 and temperature such as 4oC, 24oC and 50oC for 30 min. Different dye concentrations and adsorbent dosages were also carried out to find out optimum level. Results showed that, maximum adsorption was obtained at pH 7 at 24oC for physically activated carbon. For chemically activated carbon, it was found to be 5 pH and 24oC in which maximum adsorption was achieved. Optimum adsorbent dosage was estimated as 2g/100 ml of dye solution for both physically and chemically activated carbon and the dye concentration was found to be 0.1µg/ml.
