Abstract
Proceso para la recuperación de emulsicantes fluorados a partir de una fase acuosa, que además del emulsicante contiene pequeñas cantidades de partículas de polímero uorado, caracterizado porque se determina un valor superior de concentración de un material con actividad superfcial no iónico, por debajo del cual no se produce ninguna disminución ulterior en la desorción del emulsifdicante fiado a un cambiador de aniones, la fase acuosa se ajusta a una concentración de agente con actividad superficial no iónico entre el valor superior de concentración así determinado o una concentración inferior, ecaz todavía para la evitación de una coagulación de las partículas de polímero, la fase acuosa así ajustada se pone en contacto con una resina cambiadora aniónica, a n de activar la adsorción del emulsicante en la resina cambiadora y el emulsificante se libera de la resina cambiadora.
