Aggregation effects at interaction of organic dyes with surfactants.

Brazil / Бразилия

Aggregation phenomena at interaction of charged organic dyes with surfactants were studied with optical absorption and resonance light scattering spectroscopies and surface tension ring technique. The 1000-fold CMC reduction was observed, and the mixed dye-surfactant micelles formation, as well. The crucial role of electrostatic attraction between surfactant and dye molecules was demonstrated.
