Different kinds of carbon (Raw date stone, baked date stone and activated carbon) were prepared and characterized as inexpensive, high surface area, large micropore volume and Effective adsorbents. Material characterization was done using XRD, SEM-EDAX, FTIR and UV-Vis spectroscopy. The activated carbon (AC) possesses a surface area of 571 cm 2 .g −1 . The micropore volume and total pore volume of AC were found to be 0.4785 cm 3 .g −1 and 0.7267 cm 3 .g −1 respectively. The effect of backing temperature and activation treatment on surface area and micropore volume were studied. Taguchi factorial design method was used to get the maximum MB dye adsorption onto the surface of AC sorbent. Contact time (60 min), initial dye concentration (10 mmol), adsorbent dosage (0.25g) and solution temperature (293°K) were found to be the best conditions for the more effective absorption process.
