Claims (3)

  1. 양극 및 음극 부분이 양이온 교환막에 의해 분리된 전해 전지에서 알카리 금속 일크롬산염 및/또는 알카리금속 이크롬산염 용액을 전해시켜 알카리 금속 이크롬산염 및/또는 크롬산을 제조하는 방법에 있어서, 양이온 교환 그룹으로서 설폰산 그룹을 지니는 과플루오르화된 중합체를 기본으로하는 양이온 교환 단일층막 존재하에서 전해를 수행하고, 전지의 음극 부분의 PH가 4 내지 14인 수용액을 생성시킴을 특징으로 하는 방법.
  2. 제1항에 있어서, 수용액이 일크롬산 나트륨 및/또는 이크롬산 나트륨 및/또는 탄산나트륨을 함유하는 용액인 방법.
  3. 제1항에 있어서, 이크롬산 나트륨을 함유하는 수용액의 PH가 6 내지 7.5인 방법.
