Article Preview

Activated carbons with good spherical shape were prepared from polystyrene-derived ion exchange resin D001 having various divalent cations of Mg2+, Mn2+, and Fe2+ by CO2 activation at 800 °C for 1.0 h. The resins having univalent cation such as Na+ became fragmentized after activation, which can be attributed to their poorer thermostability than that having divalent cation. The resultant spherical activated carbon SACMg has the largest specific surface area (SBET) of 1025 m2 g-1, total pore volume (Vt) of 0.781 cm3 g-1 and mesopore volume (Vme) of 0.510 cm3 g-1. SACMg, SACMn, and SACFe all have high mesopore fraction of 65.3%, 61.0, and 59.8%, respectively.
