Ferrocyanide-음이온 교환수지에 의한 모의 토양제염 폐액 처리
Treatment of Simulated Soil Decontamination Waste Solution by Ferrocyanide-Anion Exchange Resin Beads
Abstract
Preparation of ferrocyanide-anion exchange resin and adsorption test of the prepared resin on the Cs$ion were performed. Adsorption capability of the prepared resin on the Csion in the simulated citric acid based soil decontamination waste solution was 4 times greater than that of the commercial cation exchange resin. Adsorption equilibrium of the prepared resin on the Csion reached within 360 minutes. Adsorption capability on the Csion became to decrease above the necessary Coion concentration in the experimental range. Recycling test of the spent ion exchange resin by the successive application of hydrogen peroxide and hydrazine was also performed. It was found that desorption of Csion from the resin occurred to satisfy the electroneutrality condition without any degradation of the resin.
