Abstract

Adsorption characteristics of cesium ions on zeolite and prussian blue (PB) porous inorganic materials were evaluated and cesium ion adsorption nonwoven fabric was prepared using zeolite and PB. Zeolite showed better adsorption performance for cesium ions in high concentrations, whereas PB showed higher adsorption performance at low concentration, ultra low concentration, acid/base contaminated waters. The lower the concentration of polluted water, the higher the cesium ion adsorption efficiency of PB. It was found that PB particles had a size less than half of that of zeolite after particle grinding. Cesium ion adsorption nonwoven fabrics fabricated using zeolite and PB particles were prepared and their adsorption efficiencies of cesium ions were compared. As a result, the adsorption efficiency of the nonwoven fabric fabricated using PB was better.


제올라이트와 prussian blue(PB)를 포함한 다공성 무기물의 세슘 이온의 흡착 특성을 평가하였으며 이 결과를 바탕으로 세슘 이온 흡착부직포를 제조하였다. 세슘이온에 대한 흡착성능은 제올라이트의 경우 고농도 오염수에서, PB는 저농도, 초저농도, 산/염기 오염수에서 높게 나타났다. 오염수의 농도가 낮아질수록 PB의 세슘이온 흡착효율이 높아진다는 것을 확인하였다. 입자 미세화를 통해 제올라이트 대비 절반 이하의 크기를 가지는 PB 입자를 얻을 수 있었으며 이를 이용하여 제작된 제올라이트와 PB 흡착부직포의 흡착효율을 비교한 결과 PB가 흡착제로 사용된 흡착부직포의 흡착효율이 더욱 높게 나타났다.
