Summary, etc. Highly porous activated carbon fiber with excellent surface area has been prepared using silk cotton fiber as a precursor. The Activated Silk Cotton Fiber (ASC) has well developed porosity with rose flower like structure. The BET surface area of the prepared adsorbent is 1041.08 m<sup>2</sup>/g with a total pore volume of 0.4944 cm<sup>3</sup>/g. The adsorption capability of the prepared adsorbent ASC has been analyzed using methylene blue (MB) dye. The effect of <em>p</em>H indicates that ASC has its maximum adsorption at a <em>p</em>H of 10. On analyzing the kinetics of MB adsorption, the pseudo-second order kinetic model describes the adsorption with good r<sup>2</sup> value of 0.9895 &lt; r<sup>2</sup> &lt; 0.9997. The maximum Langmuir monolayer adsorption capacity is found to be 80.65 mg/g at 45°C. The experimental results and the thermodynamic studies prove the physisorption nature of MB adsorption onto ASC.
