The retarding effect of gemini cationic surfactants in acrylic dyeing with a cationic dye (methylene blue) was studied by using UV-Vis spectroscopy. The dye adsorption rate increases with increasing temperature. The retarding action of gemini cationic surfactants is much stronger than that of the corresponding monomeric surfactants. In this work, a new empirical kinetic model based on simultaneous first and second order has been proposed. The kinetic of acrylic dyeing with a cationic dye at different temperatures and in the presence of monomeric and gemini cationic surfactants was studied by using different empirical equations. The proposed equation showed a very good correlation with experimental data in comparison to the previous ones.
