Mg/Ca계 층상이중수산화물의 수용액내에서의 이온교환 특성에 관한 실험적 연구

Abstract

Chloride ions ingress continuously in reinforced concrete through pores of it by Cl-. Recently, new materials removing harmful anions have been developed. Layered double hydroxides(LDH) has an excellent ability to remove harmful anions because various anions can be adsorbed in the interlayer space between divalent and trivalent cations. In this study, Ca/Al-NO3 and Mg/Al-NO3 LDH were prepared by using a co-precipitation method. Experiments for binding chloride ions of LDH were conducted by using potentiometric method.
