Abstract	트리아자크라운 화합물, 1,7-dioxa-4,10,13-triazacyclopentadecane trihydrobromide salt(N3O2-3-HBr)을 합성하였다. 그리고 이 화합물을 Merrifield peptide resin에 결합시켜 새로운 이온교환체를 만들었다. 이 새로운 이온교환체의 이온교환용량은 3.2meq/g이었다. 그리고 이 이온교환체에 대한 알칼리 및 알칼리 토금속 이온들의 분포계수를, 여러 농도의 염산 용액 중에서 측정하였다. 또한 여러 염산 농도하에서의 알칼리 및 알칼리 토금속 이온들의 이온교환작용을 논의하였다. The triazacrown compound, 1,7-dioxa-4,10,13-triazacyclopentadecane trihydrobromide salt (Na3O2-3HBr) was synthesized. And this compound was used to synthesize the new ion exchanger, which combined with Merrifield peptide resin. This new ion exchanger had a capacity of 3.2 meq/g dry resin. And the distribution coefficients of alkali and alkaline earth metal ions on this ion exchanger in the various concentrations of hydrochloric acid were determined. The ion exchange behaviors of alkali and alkaline earth metal ions in the various hydrochloric acid concentrations are, also, discussed.
