초록
수용액에서 음이온을 제거하기 위하여 다양한 종류의 유기/무기 복합음이온교환수지를 제조하였다. 제조된 음이온교환수지들은 질소흡탈착 실험, 적외선분광실험, 원소분석 등을 통하여 그 특성을 조사하였다. 또한 제조된 음이온교환수지의 음이온 교환 특성을 조사하기 위하여 배치(batch) 실험과 키네틱(kinetic) 실험을 수행하였다. 제조된 시료들 가운데 트리메틸암모늄 기능기를 사용했을 때보다 트리부틸암모늄 기능기를 사용하였을 때 더욱 큰 흡착량을 나타내었는데, 이것은 호프마이스터 효과와도 부합된다. 또한, 소수성기를 다량 보유하고 있는 계면활성제인 헥사데실아민도 소수성 음이온에 대한 교환능이 있는 것을 알 수 있었다.
Organic-inorganic hybrid mesoporous anion-exchange resins were prepared for the adsorption of anions from aqueous solutions. The prepared samples were characterized using nitrogen adsorption-desorption measurements, Fourier transform infrared (FTIR) spectroscopy, and elemental analyses. Batch and kinetic experiments were performed to examine the anion-exchange performances of the prepared samples. Among the prepared samples, the hybrid mesoporous anion-exchange resins functionalized with tributylammonium groups showed higher adsorption capacities for perrhenate ions than did the resin functionalized with trimethylammonium groups. The surfactant, hexadecylamine, which had hydrophobic alkyl chains, also showed affinity for hydrophobic perrhenate anions.
