摘要

The process of treatment of effluents containing dyes with cationic reverse micelles of fatty acids in organic solvents recovered.It is well known that treatment of wastewater contaminated with cationic dyes for the textile industries and washing of fabrics can be achieved through the addition of anionic surfactants in PR.Are here of organic solvents immiscible with water such as isopentanol. In the case of reverse micelles are formed consisting of dyes / surfactants that are in the organic phase is separated from the aqueous phase.After physical separation of immiscible phases, the aqueous presents efficiency of clarification of 98% and the organic concentrated dye / surfactant.The clarified water still contains a small amount of pollutants are eliminated by fototratamentos.However, despite getting the clarified water, the organic phase is the source of high pollution, toxic and is not found in the literature a proper disposal of same.Thus,The present invention is aimed at the recovery of the organic solvent through the use of oxidizing acids and their reuse in ongoing and subsequent stages in the treatment of other waves of the effluent aquosThe.In addition, alkyl carboxylic acids have proven to be efficient when used as anionic surfactants in the formation of reverse micelles and have the advantage of being biodegradable.Lower cost compared to those already in use and in the stage of recycling of the organic solvent requires a smaller quantity of acids.
