Title: A new granular composite with high selectivity for cesium ion prepared from phosphomolybdic acid hydrate and inorganic porous material

Abstract

Ammonium molybdophosphate (AMP) was incorporated in the porous alumina matrix (JA) by successive impregnation with H{sub 3}Mo{sub 12}O{sub 40}P and NH{sub 4}NO{sub 3}. The loading percentage of AMP crystals on JA increased with the repetition times of impregnation. The distribution coefficients of Cs{sup +} on AMP-loaded granular composite (JAAMP) was above 10{sup 4} cm{sup 3}/g in the presence of 1 mol/dm{sup 3}H{sup +}, while those of other nuclides were less than 10, indicating high selectivity of JAAMP to Cs{sup +}. The separation factor of {sup 137}Cs to other nuclides ({sup 85}Sr, {sup 60}Co, {sup 152}Eu, {sup 241}Am, {sup 22}Na) ({alpha}{sub Cs/Sr;Co;Eu;Am;Na} = KJ{sub d,Cs}/K{sub d,Sr;Co;Eu;Am;Na}) was estimated to be above 10{sup 3}. The breakthrough curve for Cs{sup +} through the column packed with JAAMP exhibited a symmetrical S-shaped profile, and this exchanger proved to be effective for the selective isolation of radiocesium from a simulated high-level liquid waste.
