dc.description.abstract | 용액열량계를 이용하여, 25℃ 메탄올 용액에서 dibenzo-16-crown-5(DB16C5)의 유도체들과 금속이온과의 착물형성에 관한 열역학적인 파라미터인 log K, ΔH, TΔS를 결정하고, dibenzo-16-crown-5의 유도체들을 운반체로 사용하여 벌크액체막과(bulk liquid membrane, BLM) 지지액체막(supported liquid membrane, SLM) 실험을 통하여 금속이온의 이동현상을 관찰하였다. BLM과 SLM에서 운반체로 DB16C5유도체를 사용했을 때 Ag+ 이온이 많이 이동되었고 다른 금속이온들은 약간 이동된 것으로 관찰되었다. 액체막을 통한 그속이온의 이동에서 중요한 파라미터로 작용하는 인자는 리간드의 구조, 곁가지의 길이, 주개원자의 수와 종류, 안정도상수, 리간드의 농도 등을 들 수 있다. | - |
dc.description.abstract | The thermodynamic parameters for the interaction of metal ions with dibenzo-16-crown-5 and its derivatives have been determined by solution calorimetry in methanol at 25℃. Thermodynamic properties of log K, ΔH, and TΔS have been determined for the complexation of metal cations by dibenzo-16-crown-5 and its derivatives. Dibenzo-16-crown-5 and its derivatives have been studied as metal cations carrier in bulk liquid membrane (BLM) and supported liquid membrane (SLM) system. Ag+ has been much more transported using dibenzo-16-crown-5 derivatives as carriers and several other metal cations have been small transported using carrier in BLM and SLM system. Ligand structure, the length of side arm, donor atom, stability constant, and carrier concentration are also important parameters in the transport of cations. | - |
