초록

0.25∼0.35 mg/㎡로 고정화된 이산화티타늄을 이용하여 수용액으로부터 구리이온을 효율적으로 제거할 수 있는 조건을 제시하기 위한 실험을 실시하였다. 구리이온의 제거효과는 pH 값과 온도가 높아질수록 증가하였다. 나트륨이온이 없는 조건에서 구리이온 제거효과는 높았으나 Na(+)이온농도 2 mg/L의 조건에서 급격히 낮아졌고 Na(+)이온농도 8 mg/L 이상의 조건에서는 제거효과가 거의 없었다. 아나타제형 이산화티타늄보다 루타일형 이산화티타늄의 구리이온 제거효과가 높았으며 아나타제형 이산화티타늄 50%와 루타일형 이산화티타늄 50%를 혼합한 경우의 구리이온 제거효과가 가장 높았다.

We performed the experiments to study an efficient condition for copper-ion removal using the immobilized titanium dioxide with 0.25∼0.35 mg/㎡ in aqueous solutions. The removal of copper ion increased with increased value of pH and temperature. The removal effect increased at zero Na(+) mg/L, but it decreased rapidly at 2 Na(+) mg/L. The removal effect was rarely observed over 8 Na(+) mg/L. The removal effect of copper ion by the rutile-type titanium dioxide was higher than that by the anatase-type titanium dioxide, while that by the mixture of 50% anatase and 50% rutile was highest.

Keywords:Copper ion(Ⅱ);Immobilized titanium dioxide;aqueous solutions;pH;Temperature
