초록

본 연구에서는 폐수중에 함유된 암모늄 이온을 전기투석 방법으로 회수하기 위하여 불균질 이온교환막을 압축성형 방법으로 제조하였다. 설폰화 양이온교환수지의 설폰화도는 설폰화제인 chlorosulfonic acid의 함량이 증가함에 따라 증가하였고, 최대 설폰화율은 10 vol%일때 3.32 meq/g이었다. 불균질 이온교환막의 인장강도와 신장률은 이온교환수지의 함량이 증가함에 따라 각각 감소하였으며 인장강도는 LLDPE 막이 가장 높게 나타났으며, 신장률의 경우 EVA 막이 가장 높게 나타났다. 불균질 이온교환막의 함수율은 이온교환수지의 함량이 증가함에 따라 증가하였으며 이온수송수는 PE 막의 경우 최대 0.973이었고, 전기저항값은 LLDPE막이 가장 낮게 나타났으며 수지의 함량 70 wt%일때 10.36 Ω/cm2 이었다.

Heterogeneous membranes were prepared by compression molding for the recovery of ammonium ion from waste water. Degree of sulfonation for sulfonated ion exchange resin increased with increasing amount of chlorosulfonic acid. It was 3.32 meq/g at 10 vol%. The tensile strength and elongation of the heterogeneous membrane was decreased with increasing contents of ion exchange resin. The tensile strength for LLDPE matrix membrane was the highest and also the elongation for EVA matrix membranes were the highest. The water content of heterogeneous membrane was increased with increasing contents of ion exchange resin. The maximum value of transport number for PE matrix membrane was 0.973. The electrical resistance of LLDPE matrix membrane was the lowest. It was value of 10.36 Ω/cm2 at 70 wt% resins.
