Studies on Interaction of Non-Ionic Surfactants with Some Acid Dyes by Spectrophotometric Method
نویسندگان
چکیده
The interaction of non-ionic surfactants in aqueous solutions containing some acid dyes has been studied spectrophotometrically. The spectral shift suggests that interaction decreases with increase in sulfonic acid grpup and increases. with ~crease in the hydrophobic character of the dye molecule as well as with increase in the number of ethylene oXIde umt of the surfactants, The results are explained in terms of definite binding of dye with surfactant, probablyin the form of complex ion.

Thermodynamic Study of the Ion-Pair Complexation Equilibria of Dye and Surfactant by Spectral Titration and Chemometric Analysis
Surfactant-dye interactions are very important in chemical and dyeing processes. The dyes interact strongly with surfactant and show new spectrophotometric properties, so the UV-vis absorption spectrophotometric method has been used to study this process and extract some thermodynamic parameters. In this work, the association equilibrium between ionic dyes and ionic surfactant were studied by a...

The purpose of this study was to determine the acid dissociation constants (pKa) of meloxicam in the presence of various surfactants including sodium lauryl sulfate (SLS) as an anionic surfactant, cetyltrimethylammonium bromide (CTAB) as a cationic surfactant and Triton® TX-100 (TX-100) as a non-ionic surfactant in different pre-determined concentrations. The related pKa was determined spec...

A spectrophotometric method for the determination of ionic surfactants with Bromophenol Blue (BPB) based on incorporation into a precipitated chitosan was studied. Cationic surfactants (CS+), such as a quaternary ammonium ion containing a long-chain alkyl group, associate with BPB2- buffered at about pH 9 to form the ion associate (CS+)2 x BPB2-. CS+ associates with anionic surfactants (AS-). I...
