Abstract
Polystyrene에 고분자 반응을 통해 염화메틸기를 도입시켜 Polychloromethylstyrene(PCMS)를 제조하였다. 본 연구에서는 가교 PCMS계 Matrix를 Rthylenediarnine(EDA), Diethyltriamine(DTA), Triethyltetramine (TETA)로 아민화시켜 염화메틸기와 디아민반응에 수반되는 site-site interaction현상을 관찰하고 별도로 상변화촉매 (Phase Transfer Catalyst;PCT)를 첨가하여 3상반응을 진행시켜 상변화촉매가 site-site interaction 에 미치는 영향을 조사하였다. 가교 PCMS의 금속 흡착능에서는 전반적으로 우수하며 특히 UO_(2)^(+2)이온은 염기 pH에서 선택적으로 100%정도의 뛰어난 흡착능을 보인다.;PCMS was synthesized by introducing chloromethyl group into polystyrene resin. Site-site interaction was inversigated by amination of crosslinked PCMS resin matrix, kinds of EDA, DTA, TETA. Adding PTC, it was examined what its effect influenced site-site interaction. In aminetron reactrons, EDA carries single coupling and DTA, TETA carry double coupling. Metal adsorption of crosslinked PCMS, regardless of kinds of diamine group has an excellent capacity, especially for UO_(2) ion was selectively adsorbed in base pH. In amination of PCMS matrix, phase transfer catalyst influedced in the extent of site-site interaction.
