Abstract

This paper reports a study of the association between the anionic dye bromophenol blue BPB and nonionic surfactant octylphenol polyoxyethylene ether 10 OP–10 in aqueous solution Addition of OP–10 causes marked changes in the characteristic absorption peaks of BPB indicating that interactions exist between BPB and OP–10 We calculated thermodynamic parameters for the interaction by establishing a reasonable physical model of the association Moreover an indepth study of variations in the absorption spectrum shows that the value of absorbance at the maximum absorption peak changes systematically with increasing OP–10 concentration The critical micelle concentration values determined from measurements of electric conductivity are consistent with the variations in regions of the spectrum In order to study the dispersion of dye in OP–10 aqueous solution the water–micelle partition coefficient was determined while the value of Gibbs energy of partition was calculated from the value of the partition coefficient
