Manufacturing of Nonwoven Fabrics Containing Porous Inorganic Materials and the Evaluation of Their Cesium Adsorption Performance

초록

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.
