초록
본 연구는 벌크 중합을 이용하여 하이퍼브랜치 poly(styrene-co-divinylbenzene)(이하 PSD로 칭함)을 합성하고, 이를 설폰화하여 이온교환 용량이 큰 양이온교환체를 합성하였다. 또한 FT-IR, 1H-NMR, 및 GPC 분석을 통하여 하이퍼브랜치 PSD 이온교환체의 분자량 및 구조 확인을 하였다. 하이퍼브랜치 PSD의 분자량과 점도는 DVB의 양이 증가함에 따라 모두 증가하였으며, 각각 최대값이 9410 g/mol과 338 cP로 나타났다. 또한, 가교제의 양이 증가함에 따라 반응속도가 증가하였으며, PSD의 용해도는 감소하였고, DVB 농도가 0.1 mol%에서 용매 100 mL에 22 g이 용해되었다. 또한, 하이퍼브랜치 PSD 이온교환체의 함수율과 이온교환 용량은 설폰산기의 함량이 증가함에 따라 증가하였으며, 각각 최대 18.2%, 4.6 meq/g이었다. 구리 및 니켈에 대한 흡착이 40분 이내에 거의 100% 이루어 졌다.
In this study, the hyper branched poly(styrene-co-divinylbenzene) (PSD) was synthesized by bulk polymerization and the cationic exchanger with high ion exchange capacity was prepared by sulfonation. The structure of hyper branched PSD ion exchanger was investigated by FT-IR, 1H-NMR spectroscopy, and GPC analysis. The molecular weight, viscosity of hyper branched PSD increased with DVB content, which have the maximum values of 9410 g/mol and 338 cP, respectively. And the reaction rate also increased with cross-linker content. As DVB content increased, the solubility of PSD decreased having the maximum value of 22 g with 0.1 mol% DVB. The water content and ion exchange capacity of the hyper branched PSD ion exchanger increased with the amount of sulfuric group. Their maximum values were 18.2% and 4.6 meq/g, respectively. The adsorption of copper and nickel ion was completed within 40 min.
