Studies in the Aggregation of Disperse Dyes

The aggregation of disperse dyes in aqueous solution along with surfactants has been studied spectrophotometrically by Klotz’s method and polarographically employing Iikovic’s equation by diffusion coefficient method. The extent of complex formation between dye and surfactants have been studied and compared with the determination of aggregation numbers from polarographic measurements.
