Spectrophotometric study of the interaction of some triphenylmethane dyes and 1-carbethoxypentadecyltrimethylammonium bromide.
The effect of the cationic surfactant 1-carbethoxypentadecyltrimethylammonium bromide at above and below its critical micelle concentration on the absorption spectra and the values of the apparent dissociation constant pK(2) of the dyes Phenol Red, Bromophenol Blue and Bromocresol Green has been studied, along with the influence of a strong electrolyte (NaCl) on the effects produced by the presence of surfactant micelles in the dye solution.
