Abstract

On décrit la séparation d'un contaminant à partir d'un substrat portant ce contaminant. Ce procédé consiste à mettre le substrat au contact de dioxyde de carbone fluide renfermant une espèce amphiphile de sorte que le contaminant s'associe à l'espèce amphiphile et est entraîné par le dioxyde de carbone fluide, puis à séparer le substrat du dioxyde de carbone fluide, et à séparer le contaminant du dioxyde de carbone fluide.
