초록

원자로계통수 조건(300℃, 160kg/㎠)에서 방사성 부식생성물 중 ⁶⁰Co를 제거하기 위한 원전계통수정화용 고온흡착제의 흡착메카니즘 및 제조방법을 알아 보았고, Fe-Ti-O, TiO₂, ZrO₂ 등의 흡착제를 공침법, 금속알콕사이드가수 분해법, 졸겔법에 의해 제조하였다. 고온수에서 이들 흡착제의 Co²⁺ 흡착특성을 Autoclave를 이용한 회분식 흡착실험으로 살펴 보았으며, Fe-Ti-O 흡착제 제조시 소결온도 변화에 따른 Co²⁺ 흡착용량과 TiO₂흡착제 제조시 pH 변화에 따른 흡착용량 및 비표면적 등을 알아 보았다.

To remove the solube corrosion products, mainly ⁶⁰Co under PWR reactor coolant conditions(300℃, 160kg/㎠), the adsorption mechanism and preparation method of high-temperature adsorbents for reactor water purification were studied. Fe-Ti-O, TiO₂ and ZrO₂, adsorbents were prepared by coprecipitation, hydrolysis of metal alkoxide and sol-gel method. The Co²⁺ adsorption characteristic of these adsorbents in high temperature water were investigated in batch adsorption experiment by a stirred autoclave. The effect of sintering temperature on Co²⁺ adsorption capacity of Fe-Ti-O adsorbent and the effect of preparation pH on Co²⁺ adsorption capacity and specific surface area of TiO₂ adsorbent are reported.
