“…24 In the recent study, the interaction of CTAB (cationic surfactant) with MR is attributed to azo form at λabs = 414 nm whereas the interaction of AOT (anionic surfactant) with MR is subjected to hydrazone form λabs = 519 nm. 14 In the present work, the interaction of cationic surfactant (DTAB) with azo dye (MR) is studied through the spectrophotometric method. In the case of MR, due to its photo-switchable, its azo(basic) form attracts ionized surface-active agents.…”

[12][13] The present study describes the azo-hydrazone tautomerism using the absorbance techniques along with the observation of binding constant and Gibb's free energy of binding of DTAB on MR which will facilitate the advancement in the molecular design of similar derivatives, specifically a -COOH group azo dye through the photosensitized system in optical tenability.…”

“…[6][7][8][9][10][11] There are no specified studies of azo dye methyl red with cationic surfactant dodecyl trimethyl ammonium bromide using various methods. [12][13][14][15][16][17] For detailed analysis, we reviewed in literature 13 that the effect of cationic surfactants on the dissociation constant of methyl red by spectrophotometric technique. The absorbance peak of methyl red was decreased drawn after 10 and 20 min of treatment in water due to photodegradation through kinetic analysis and complete photodegradation of the 35 min treatment, which is based on azo dye photosensitization.…”

The interaction of azo dye methyl red (MR) with dodecyl trimethyl ammonium bromide (DTAB) has been studied spectrophotometrically through azo-hydrazone tautomeric behavior of MR for a series of the ethanol-water system (0.1, 0.2, 0.3 and 0.4 volume fractions of ethanol) at room temperature. Critical micelle concentration was determined using the conductometric technique with increased ethanol volume influenced by solvent polarity and architectural flexibility of methyl red. The azo form of methyl red brings electrostatic interaction with cationic surfactant through the adsorption phenomenon. The binding parameters were calculated with the aid of a modified Benesi-Hildebrand equation.

“…There have been some spectrophotometric measurements of dyes in the presence of surfactants 12,[20][21][22][23][24][25][26][27] and particularly, even some studies of methyl red with AOT were noticed in the literature. [28][29][30][31] Our aim was to see the spectrophotometric measurements of methyl red in AOT/methanol and AOT/methanol/water systems. However, there is no literature on the UV-Vis study of methyl red in AOT/methanol and with increasing amounts of water in methanol.…”

"This paper deals with the interaction of sodium dioctylsulfosuccinate (AOT) and methyl red (MR) by UV-Vis spectrophotometry at 298.15 K. The concentration of AOT varies from 0 to 0.12530 mol/kg and the concentration of methyl red is 3.71×10-5 M. Here, water concentration is defined by the R parameter. The R parameter in this study varied from 0 to 20. Two intense absorption bands were observed within the 380 to 540 nm wavelength of methyl red in methanol. Band 1(380 to 450 nm) of methyl red contains a higher absorbance peak than band 2(450 to 540 nm). When the concentration of AOT increased, band 1(380 - 450 nm) of methyl red decreased the absorbance peak, whereas band 2 (450 to 540 nm) of methyl red increased the absorbance peak with increasing AOT concentration. Band 1 shows a hypochromic shift of methyl red with an increase in AOT concentration, whereas band 2 shows a hyperchromic shift of methyl red with an increase in AOT concentration. On comparing the absorbance versus concentration graph for different R parameters, we observed that absorbance increases with the increase in the R parameter. The binding constant and distribution constant were calculated using a non-linear regression procedure (NLREG). The experiment shows the effect of methanol, AOT and water concentration on methyl red."
