Dye–surfactant interaction: solubilization of styryl pyridinium dyes of varying alkyl chain in alfa-olefinic sulfonate and linear alkyl benzene sulfonate solutions

Synthesis and Surface Active Properties of Gemini Cationic Surfactants and Interaction with Anionic Azo Dye (AR52)

“…Many techniques have been used for qualitative and quantitative description of dye-surfactant interactions, i.e., potentiometry [15,16], ordinary conductimetry [17,18], or with ion selective electrodes [19,20], but the most widely used are spectroscopical methods [21][22][23][24][25][26].…”

Dye–surfactant interaction in aqueous solutions

“…potentiometry [3,4], conductometry [5,6], or ion selective electrodes [7,8]. The most often used method to investigate dye-surfactant interactions is spectrophotometry [9][10][11][12][13][14].…”

Fluorescent probe studies of micropolarity, premicellar and micellar aggregation of non-ionic Brij surfactants

“…Various methods for the determination of their critical micellar concentrations (CMC) have been described in the literature [7][8][9][10]. It has been observed in many cases of surfactants that the occurrence of the micellar phase is preceded by the formation of different comparatively smaller aggregates known as premicellar aggregates [11][12][13][14][15][16]. Hadgiivanova et al developed a thermodynamic model to study the aggregation mechanism [17,18].…”

“…In many cases, molecular probes have been used to study the premicellar domains of some surfactants [14,15,22]. One common difficulty faced in the use of these fluorescent probes was their insufficient sensitivity toward the changes in different phases of premicellar aggregates.…”
