Abstract

Interactions of amaranth dye [Amr] with cetyltrimethylammonium ammonium bromide [CTABr] have been investigated using UV-spectrophotometric technique. Finding from the variation absorption spectral shows that absorbance values at the highest peak changes on addition of CTABr indicating that interaction exist between Amr and CTABr. The binding constant [Kb] between the micellar/water phases has been obtained using appropriate model from which the thermodynamic parameters have been calculated at different temperatures. The binding decreases with increasing temperatures. The free energy [ΔG0], entropy [ΔS0] and enthalpy [ΔH0] changes regarding binding process are spontaneous, exothermic and enthalpy driven.
