Oculau00e7u00e3o ionic surfactants of anionic and calcium salts to create? Hydrophobic hollow capable of removing the dye and? Uente using biodegradable surfactants.The process consists in adding an anionic surfactant and? Uente textile, followed by addition of calcium salts, by promoting the reaction of surfactant with the calcium and the interaction of the new surfactant with the dye forming an insoluble surfactant in the form of a snowflake impregnated with the dye, after decantation and / or filtration leads to a and?
