Claims (8)
- 플루오르화 유화제 및 소량의 플루오로중합체 입자를 함유하는 수성상으로부터 플루오르화 유화제의 회수 방법으로서,비이온성 계면활성제의 농도 상한치는 음이온 교환기에 결합된 유화제의 탈착이 더 이상 감소하지 않는 농도 이하로 결정되고,수성상에서 비이온성 계면활성제의 농도는 상기 방식으로 결정된 농도 상한치와 중합체 입자의 응집을 저해하는 데 여전히 유효한 더욱 낮은 농도 사이로 조정되며,상기 방식으로 조정된 수성상은 음이온 교환 수지와 접촉하게 되어, 교환 수지상으로 유화제의 흡착이 일어나게 되고,유화제는 교환 수지로부터 방출되는 것인 방법.
- 플루오르화 유화제 및 소량의 플루오로중합체 입자를 함유하는 수성상으로부터 플루오르화 유화제의 회수 방법으로서, 수성상에서 비이온성 계면활성제의 농도는 10 ppm과 중합체 입자의 응집을 저해하는 데 여전히 유효한 보다 낮은 농도 사이로 조정되고, 상기 방식으로 조정된 수성상은 음이온 교환 수지와 접촉하게 되어 교환 수지상으로 유화제의 흡착이 일어나게 되고, 유화제는 교환 수지로부터 방출되는 것인 방법.
- 제2항에 있어서, 상기 비이온성 계면활성제의 농도는 5 내지 0.1 ppm인 방법.
- 제1항 내지 제3항 중 어느 한 항에 있어서, 상기 비이온성 계면활성제는 비방향족 물질인 방법.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 상기 비이온성 계면활성제는 지방 알코올 옥시에틸레이트인 방법.
- 제1항 내지 제5항 중 어느 한 항에 있어서, 유효량의 유기 응집제를 수성상에 첨가하여 거의 모든 플루오로중합체 입자를 침전시키는 것인 방법.
- 제6항에 있어서, 상기 응집제는 유기 양이온 응집제인 방법.
- 제6항 또는 제7항에 있어서, 상기 응집제는 처리되거나 미처리된 수성상에 첨가되는 것인 방법.
