초록

1%, 2%, 5% 및 15%의 가교도를 가진 클로로메틸화된 스타이렌-1, 4-디비닐벤젠에 OenNdien-H4 거대고리 리간드를 공중합반응으로 결합시켜 이온교환 수지를 합성하여 우라늄(UO22+), 칼륨(K+), 네오듐(Nd3+) 금속 이온들의 흡착 특성을 여러 가지 실험 조건하에서 조사하였다. 이들 합성수지의 확인은 염소 함량과 원소 분석 그리고 IR-스펙트럼으로 하였으며, 수지에 대한 금속 이온들의 흡착에 미치는 pH, 시간 그리고 수지의 가교도에 따른 영향들을 조사한 결과 우라늄 이온은 pH 3 이상에서 큰 흡착률을 보였으며, 금속 이온들의 흡착 평형은 2 h 정도였다. 한편, 메탄올용액에서 수지에 대한 흡착 선택성은 우라늄(UO22+) > 칼륨(K+) > 네오듐(Nd3+) 이온이었고, 금속 이온의 흡착력은 1%, 2%, 5% 및 15%의 가교도 순이었다.

Ion exchange resins have been synthesized from chloromethylated styrene-1,4-divinylbenzene (DVB) with 1%, 2%, 5% and 15%-crosslinkage and macrocyclic ligand of OenNdien-H4 by copolymerization. The adsorption characteristics of uranium (UO22+), potassium (K+) and neodymium (Nd3+) metallic ions have been investigated. The synthesis of these resins was confirmed by content of chlorine, element analysis, and IR-spectrum. The effects of pH, time, and crosslinkage on adsorption of metallic ions were also studied. The uranium ion showed the fast adsorption on the resins above pH 3. The optimum equilibrium time for the adsorption of metallic ions was about two hours. The adsorption selectivity determined in methanol solution was in increasing order uranium (UO22+) > potassium (K+) > neodymium (Nd3+) ion. Moreover, the adsorption was increased with the crosslinkage concentration in order of 1％, 2％, 5% and 15％-crosslinkage resin.

Keywords:styrene;divinylbenzene;crosslinkage;macrocyclic ligand;OenNdien-H4
