Preparation and Characterization of Zeolite-Containing Composite Sheets for Decontamination of Radioactive Ions Dissolved in Water (II)
Source abstract
Abstract
The efficient and effective decontamination of radioactive ions from soil and water has been required after the Fukushima Daiichi Nuclear Power Station accident. In this study, we prepared an A-type zeolitecontaining sheet and clinoptilorite-containing sheet for decontamination of radioactive strontium ion (Sr2+), and evaluated their adsorption behavior of Sr2+ under various conditions. In the case of the A-type zeolite containingsheet,thepartitioncoefficientofSr2+dissolvedinsimulatedseawaterwas8.8×102,andthe maximumSr2+-adsorbedamountundersaturationconditionswas249mg/g.Inthecaseoftheclinoptilorite- containingsheet,thepartitioncoefficientofSr2+dissolvedinsimulatedseawaterwas2.7,andthemaximum Sr2+-adsorbedamountwasonly50mg/g.Inafiltrationexperimentusingcontinuouspassingwater,theinitial adsorptionratioofSr2+reached86%inpurewaterand38%insimulatedseawater.TheA-typezeolite- containingsheethadmoreeffectiveadsorptionbehaviorofSr2+dissolvedinbothpurewaterandsimulated seawaterthantheclinoptilorite-containingsheetundertheconditionsusedintheexperiments.
