Abstract
【解決手段】セシウムを吸着したフェロシアン化物とジオポリマーを混合して成形し、この成形物を前記フェロシアン化物の分解温度以上で焼成することにより、フェロシアン化物を分解し、かつフェロシアン化物から遊離したセシウムを焼成物内で固定させることを特徴とする。
【選択図】図3
Description
この定量分析の結果、Cs残存量(率)がOPC固化物では約84%であるのに対して、GP固化物のGP/0.6では99.2%、GP/0.9では98.7%の高いCs残存量であった。
浸出試験の手順は、焼成物を2.0mm以下の大きさに粉砕し、篩分けして、固液比が10(ml/g)となるように粉砕試料に蒸留水を添加し、回転数200rpm,振幅4cm,25℃の条件で6時間振とうを行う。
