Abstract
Titanium-based adsorbents such as TiO2 and Fe-Ti-O were prepared by hydrolysis of Ti(OC3H7)4 and alkalinizing an equimolar mixed solution of TiCL4 and FeCl2 followed by heat treatment of their hydroxides, respectively. The prepared Fe-Ti-O adsorbent was found to be stable nonstoichiometric ferrous and ferric titanium oxides with pseudobrookite and rutile structures. The Co2+ adsorption characteristics of the adsorbent in high temperature water were investigated in the autoclave.Co 2+ adsorption capacity of the Fe-Ti-O adsorbent was determined to be larger man that of TiO2 at high temperatures. The enthalpy changes of 34 and 49 kJ-mol-1 due to the adsorption of Co2+ on the TiO2 and Fe-Ti-O adsorbents indicate that the adsorption is endothermic in the experimental temperature range (15-280 ‡C). From this preliminary study, titanium-based oxides are shown to have good potential applicability for reactor water purification as high temperature adsorption media.
