본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (5)

  1. 요오드를 산화상태 7, 다시 말해 과요오드산염 형태로 산화시킨 다음, 과용오드산염을 제거함을 특징으로 하는, 요오드를 함유하는 알칼리 금속 염화물수용액의 정제방법.
  2. 제1항에 있어서, 요오드가 활성염소, 바람직하게는 하이포아염소산염으로 산화되는 방법.
  3. 제1항 또는 2항에 있어서, 과요오드산염의 제거를 염기성 매질 중에 침전시켜 수행하는 방법.
  4. 제1항 또는 2항에 있어서, 요오드의 산화 및 암모늄의 질소분자로의 산화를 동시에 수행하는 방법.
  5. 제4항에 있어서, 산화를 활성염소, 바람직하게는 하이포아염소산염으로 수행하는 방법.
