알칼리금속염화물 수용액으로부터 황산이온 제거방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (3)

  1. 황산이온을 함유하는 알칼리금속염화물의 수용액과 지르코늄가수산화물이 산성조건하에서 슬러리형으로 서로 접촉을 일으키게 됨으로써 이온교환반응에 의해 황산이온이 지르코늄가수산화물에 흡착되도록 하고, 황산이온을 흡착한 지르코늄가수산화물이 수용액으로 부터 분리되고 그 후에 다른 수용액에 분산되어 알칼리와 접촉하여 황산이온을 수용액속으로 탈착시키는 것을 특징으로 하는 알칼리금속염화물의 수용액으로 부터 황산이온을 제거하는 방법.
  2. 제1항에 있어서, 세디크래프법에 의해 측정된 지르코늄가수산화물의 평균 50중량%의 입자크기는 1 내지 20㎛인 것을 특징으로 하는 알칼리금속염화물의 수용액으로 부터 황산이온을 제거하는 방법.
  3. 제1항에 내지 제2항에 있어서, 지르코늄가수산화물의 강열감량(40℃에서 16시간 동안 건조함으로써 탈착수를 제거한 후에 지르코늄가수산화물의 감량전에 1000℃에서 1시간 동안 감열전과 후의 중량 차이의 퍼센트구분)이 3내지 40중량%인 것을 특징으로 하는 알칼리금속 염화물의 수용액으로 부터 황산이온을 제거하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
