Adsorption of Acid Dyes onto Wool in TX-100 Reverse Micelles

Abstract:

Article Preview

The non-ionic reverse micelles used for dyeing wool were prepared with a non-ionic surfactant Triton X-100 (TX-100) by injecting small amount of acid dye aqueous solution. And the adsorption properties of three water-soluble anionic acid dye including Mordant Black 9, Acid Black 234 and Acid Orange 156 onto wool in TX-100 reverse micelle were studied and compared. Then effect of W value (molar ratio of the injected water to TX-100) and pH level on dye adsorption was also investigated. The results indicate that Higher W value and Low pH level would increase the adsorption amount of the dye onto wool. The adsorption of the dye onto wool showed better agreement with Langmuir isotherm equation. Mordant Black 9 with lower molecular weight and one sulfonic group exhibited the higher adsorption capacity than the other dyes.
