국문 초록 (Abstract)

Acryloyl methyl benzo-18-crown-6 단위체는 '4-hydroxymethyl benzo-18-crown-6와 acryloyl chloride을 반응시켜 합성하였다. Poly(acryloyl methyl benzo-18-crown-6)는 벤젠용매하에서 AIBN을 개시제로하여 제조하였다. [0.001mole/L M(NO_3)_n(M^2+ =Na^+, Mg^2+, Ca^2+, Sr^2+, Ba^2+, Zn^2+, Cu^2+, Cd^2+, Mn^n+ 와 Pb^2+)]를 포함한 source phase와 거대고리 리간드 [acryloyl methyl benzo-18-crown-6와 poly(acryloyl methyl benzo-18-crown-6)]와 계면활성제 Span 80을 포함한 toluene 막 그리고 Li_4P_2O_7를 포함하는 receiving phase로 구성되어진 에멀젼 액체막계에서 source phase로 부터 금속이온들의 소멸속도를 연구하였다. 금속이온의 이동에 관한 실험에서, 각 혼합물로 부터 Pb^2+ 이온이 가장 높은 이동율을 나타내었다.

Acryloyl methyl benzo-18-crown-6 was synthesized by reacting 4'-hydroxymethyl benzo-18-crown-6 with acryloyl chloride. Poly(acryolyl methyl benzo-18-crown-6) was prepared in benzene by using AIBN as an initiator. The disapperance of metal ions from source phase as a function of time was studied in emulsion liquid membrane systems comprised in an aqueous source phase [0.001mole/L M(NO_3)_n(M^n+ =Na^+, Mg^2+, Ca^2+, Sr^2+, Ba^2+, Zn^2+, Cu^2+, Cd^2+, Mn^2+ 와 Pb^2+)], a toluene membrane containing of the macrocyclic ligand[acryloyl methyl benzo-18-crown-6 and poly(acryloyl methyl benzo-18-crown-6)] and the surfactant Span 80, and an aqueous Li_4P_2O_7 receiving phase. In the experiment for metal ions transport using this emulsioning liquid membrane, the Pb^2+ ion transport was more higher than other metal ions.
