Description
In order to use as adsorbent for removal of the soluble corrosion products, mainly Co60 under PWR reactor coolant conditions (300 deg C, 160 kg/cm2), stable ZrO2 adsorbent was prepared using sol-gel process from zirconyl nitrate, AlO adsorbent was prepared by hydrolysis of aluminum isopropoxide, and titanium tetraisopropoxide, respectively. The prepared adsorbents were calcined at various temperature and analyzed by physical properties and the Co2+ adsorption capacity. And it was shown that the Co2+ adsorption capacity of the TiO2-Al2O3 adsorbents were found to have larger than that of ZrO2 and Al2O3 adsorbents in high-temperature water. ZrO2, Al2O3 and TiO2-Al2O3 adsorbents were found to be suitable high-temperature adsorbents for the removal of dissolved corrosion products, mainly Co in PWR reactor coolant conditions. 15 tabs., 51 figs., 55 refs.
