摘要： The present invention relates to a method of treating aqueous effluents that employs an organic-solventless liquid/liquid extraction which allows the organic and metallic pollutants to be extracted by virtue of their solubilization in mixed micelles. These mixed micelles, which are formed of ionic surfactants, are capable of simultaneous extraction of the organic and metallic pollutants. The method according to the invention is simple, quick to implement and economic in terms of energy. The reduction in polluted volumes without production of new pollution is also a very advantageous result. The method makes it possible, moreover, to regenerate the surfactants for subsequent use, and also to recover the compounds extracted, which can be stored directly as ultimate waste or utilized for other purposes. The method may also be carried out as a continuous procedure, on the same site at which the effluents are produced.
