Claims (4)

  1. 피흡착물질이 이온상태 및 콜로이드상태로 존재하는 알칼리성폐액에 분말타닌을 첨가하여 주로 타닌으로 이루어져 있는 고체물질을 생성시켜 전기한 고체물질에 전기한 피흡착물질을 흡착시키는 단계와, 그후 전기한 폐액을 여과하여서 전기한 피흡착물질을 함유하고 있는 전기한 고체물질을 분리하는 단계로 구성되어 있는 것을 특징으로 하는 알칼리성 폐액의 처리방법.
  2. 제1항에 있어서, 전기한 피흡착물질은 우라늄과 토륨을 함유하는 핵연료물질인 것을 특징으로 하는 알칼리성폐액의 처리 방법.
  3. 제1항에 있어서, 전기한 타닌은 농축타닌인 것을 특징으로하는 알칼리성폐액의 처리방법.
  4. 제3항에 있어서, 전기한 농축타닌은 퀘브라쵸타닌, 아카시아타닌,맹그로브타닌, 가문비나무타닌, 갬비어타닌, 아카카테긴 및 참나무껍질타닌으로 구성되어 있는 군(群)에서 선택되는 것을 특징으로 하는 알칼리성 폐액의 처리방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
