초록

화학적 성질이 유사한 몰리브덴과 텅스텐 이온의 혼합 용액에서 한 성분을 선택적으로 분리, 회수하기 위하여 iminociacetic acid, diethanolamine, diethylenetriamine 등 세 종류의 리간드를 갖는 킬레이트 수지를 이용하였다. 각각의 킬레이트 수지에 대해 시간, pH 및 금속이온농도를 변화시키면서 회분식 실험으로 금속이온의 흡착 거동을 조사하였다. 또한, 몰리브덴 또는 텅스텐과 결합된 킬레이트 수지를 FT-IR과 H NMR으로 관찰하였다. 각 킬레이트 수지의 흡착량은 pH가 증가하면 감소하였으며, pH 2-6의 범위에서 몰리브덴 이온을 선택적으로 결합하였다. diethanolamine기를 지니는 킬레이트 수지가 pH 1-6 범위에서 몰리브덴과 텅스텐 모두에 대해 가장 큰 흡착 용량을 나타내었으나, iminodiacetic acid기를 지니는 킬레이트 수지가 몰리브덴과 텅스텐을 선택적으로 분리하기 위해 가장 좋은 결과를 나타내었다.

Three kinds of chelate resins bearing iminodiacetic acid, diethanolamine or diethylenetriamine groups have been applied to selectively separate and recover one component in a mixture of Mo and W, where their chemical properties are very similar. The adsorption behavior of metal ions was investigated for each chelate resin under various experimental conditions such as time, pH, and metal ion concentration by a batch experiment. The chelate resins associated with M or W ions were also characterized by FT-IR and H NMR. The metal uptake of each chelate diethanolamine groups showed the maximum adsorption capacity for Mo and W over a pH range of 2-6. The chelate resin with diethanolamine groups showed the best result to separate Mo and W selectively.
