Abstract: The experiments undertaken in order to understand the variables which affect the adsorption characteristics of the dye-carbon system represented the major experimental part of the investigation. The disperse dyes and activated carbon were studied with and without the auxiliary chemicals normally present in a dye effluent such as surfactants, alkaline salts, acids, and bases. To gain some understanding of the dye-carbon adsorption system, six experimental areas were investigated. These were: The effects of concentration, the effects of pH, the effects of nonionic surfactants, the effects of anionic surfactants, the effects of alkaline salts, and the effects of an alkaline salt in the presence of a nonionic surfactant. Three different classes of disperse dye were chosen for these experiments: Disperse Yellow 54, a quinonapthalone type used for batch dyeing polyester and polyester blends, Disperse Red 73, a monazo type commonly used in thermosol dyeing of polyester fabrics, and Disperse Blue 7, an anthraquinone type widely accepted by the carpet industry for dyeing nylon carpets. The powdered activated carbon used in this study was Hydrodarco C, a lignite type developed specifically for water treatment by ICI Incorporated, Wilmington, Delaware.
