The affecting factors and kinetic characteristics of antimony (Sb) adsoption onto a type of the coconut shell activated carbon were investigated in this study. The results showed that: the Sb adsorption obeyed the pseudosecondorder kinetics equation, and the coefficients of determination (R2) were higher than, inferring that this process was mainly the monolayer chemical adsorption.

· · In this work activated carbon was prepared from green coconut shells by chemical activation method. It was then characterized by XRD, SEM, FTIR and TGA. Different physical properties such as bulk density, moisture content, volatile matter content, ash content, and surface area and porosity were also determined. The activated carbon was used as adsorbent for the removal of carbon .

Abstract: The adsorption equilibrium of CO 2 was measured on coconut shell activated carbon by using a static volumetric method. Adsorption isotherms over the temperature ranged 308 K ~ 353 K were measured. The results showed that the capacities of adsorption of carbon dioxide on activated carbon at different temperatures were as follows: 308 K > 323 K > 338 K > 353 K.
