Abstract	The adsorbent materials were prepared by mixing PS and RPF using physical activation method. The starting PS consists of inorganic components of $SiO_{2},$ CaO and $Al_{2}O_{3}$ and RPF has mainly high amount of carbon. The commercial activated carbon was used as a reference material to compare with the prepared samples. The prepared samples show the crystalline phases of calcite $(CaCO_{3})$ anorthite ((Ca, Na) (Al, $Si)_{2}Si_{2}O_{8})$ and gehlenite $(Ca_{2}Al_{2}SiO_{7})$ by heating above 900degC. The sample calcined at 700degC has the highest specific surface area (49 $m^{2}/g)$ but was quite low compared with the reference material (1122 $m^{2}/g).$ The ability of the prepared samples to remove toxic ions e.g. nickel $(Ni^{2+})$ and methylene blue from aqueous solution was investigated by a batch method. The samples (showing amorphous phase) prepared at 700degC showed higher uptake ability for $Ni^{2+}$ (3.55mmol/g) ions than that of the commercial activated carbon. The main mechanisms of $Ni^{2+}$ uptake were the ion substitution. In methylene blue adsorption experiment, the adsorption capacities of obtained samples were lower (0.58 mmol/g) than the commercial activated carbon (1.03 mmol/g). These prepared materials are concluded to be a candidate for a cost effective adsorbent.
