| Outline of Final Research Achievements |
I investigated "Anti-diffusing agent" for the toxic substance. It was molded into an gel form using Mn-Fe hydroxides (Cs or As selective adsorbents) and cheap substrate (Agar, etc.). In the case of As for the toxic substance and Mn-Fe hydroxide as the adsorbent, an agar was the effective gel substrate for "Anti-diffusing agent". In the case of Cs, Prussian blue nano particles were not worked effective in an agar. But an only agar without adsorbent has dilute effects for Cs in batch test. Therefore, only gel materials expected to work effective "Anti-diffusing agent" for the toxic substance.

| Academic Significance and Societal Importance of the Research Achievements |
合成方法の簡単な沈殿法で製造したMn-Fe系吸着剤をスラリー状のまま、ゲル化剤を用いて成形した成形体においても、As吸着性能を維持出来る事がわかった。ゲル化剤を変える事で、様々な用途への適用が考えられる。
一方、ゲル化剤のみでも、十分な遮水効果が得られ、福島第一原子力発電所の地下水流入による有害物質拡散においても、十分な効果が期待できる事が分かった。
