Abstract

The aggregation behaviour of an azo dye containing a trifluoromethyl group (-FTS) in aqueous solutions has been investigated by means of visible absorption measurements. The thermodynamic parameters for aggregation were calculated from the dependence of the aggregation constants on temperature. The thermodynamic pa
