- 放射性物質で汚染された土壌の除染処理方法において、
陽性界面活性剤を含有する処理水と汚染土壌とを撹拌混合することで汚染土壌を洗浄した後に、洗浄済みの土壌と洗浄で使用した洗浄水とに分離し、洗浄水に硫黄の高分子陰イオン(S X m− (x、mは整数。))とコロイド状の硫黄とを含有する水溶液を主成分とする処理剤を添加して放射性物質を沈殿回収することを特徴とする除染処理方法。 - 前記洗浄時に、高周波振動や気泡崩壊による衝撃を加えることを特徴とする請求項1に記載の除染処理方法。
- 前記処理剤は、硫黄とアルカリ水との混合液に中性又は陰性の界面活性剤を添加した後に反応容器の内部圧力が2.5kg/cm 2 以下で内部温度が90℃以上となるまで加熱して生成することを特徴とする請求項1又は請求項2に記載の除染処理方法。
