Binding influence of sunset yellow dye on the sodium tetradecyl sulphate micelles in the presence of sodium carboxymethyl cellulose medium

Counterion Association of Ionic Drugs with Sodium Tetradecyl Sulfate in the Aqueous Medium

“…Therefore, it was chosen that the fitted value of N m was approximately equivalent to 1, and the absorbance data showed that one drug was bound to each micelle. Other studies have already reported on the variance of N m values. ,,,,,,, For instance, Caetano and Tabak used a relation similar to eq to analyze the absorbance data of the drugs trifluoperazine and chlorpromazine in aqueous cetyltrimethylammonium chloride solution, resulting in found values of N m in the variety of 0.90–1.14 for chlorpromazine and in the range of 1.00–1.12 for trifluoperazine. Pellosi et al reported values of N m around 1 for the four xanthenes dyes fluorescein, eosin Y, erythrosin B, and rose bengal B in an aqueous pluronic P-123 solution, however, they observed values of N m close to 2 in an aqueous cetyltrimethylammonium bromide solution.…”

“…Other studies have already reported on the variance of N m values. 13,14,19,28,29,32,40,41 For instance, Caetano and Tabak 45 Furthermore, the K b value was determined using the slope and intercept data from Figure 8. For DPC and CPM, the values of log K b were 2.232 and 2.837, respectively.…”

“…25−27 Our research groups are currently investigating the micellization properties of surfactants in the presence of organic additives such as ionic drugs, dyes, and polyelectrolytes in the aqueous medium. 13,14,19,28,29 Antihistaminic medications were widely used for their ability to make weakly water-soluble substances soluble in an aqueous environment. Shah and Flanagan 30 self-associations of antihistamine drug salts on the dissolution of salicylamide and acetaminophen in water-based solutions.…”

“…Many more investigators have shown in recent years which organic counterions can improve the micellization functions of surfactants in the aqueous medium, for example, tetraethyl and tetra- n -propylammonium, n -alkyl carboxylate ions and tetraalkylammonium counterions. − Our research groups are currently investigating the micellization properties of surfactants in the presence of organic additives such as ionic drugs, dyes, and polyelectrolytes in the aqueous medium. ,,,, …”

Effect of CTAB premicelle and micelle formation on Bromophenol Blue spectra

“…[3] The study of interactions between surfactants and dyes in aqueous solutions has attracted significant interest in the recent years because of their relatively complex behavior and widespread applications. [1,[4][5][6][7][8] This investigation is of great importance to various chemical research area, including photosensitization, [9] medicinal applications, [10,11] photographic industry [12] and ion detection. [13] Consequently, it has emerged as a significant research area, [14][15][16][17][18][19][20] especially as surfactants assist the dyeing process in dyeing industry.…”
