“…The conductivities were recorded 2 min after each dilution, and at least three entries were taken as an average value. The CMC values were recorded in a conductivity versus different surfactant concentrations plot [63–67]. The CMC values measured in our study (H 2 O and H 2 O + ninhydrin + methionine) are shown below.…”

The influence of double-headed gemini was examined in the present study by studying the amino acid methionine mixed with ninhydrin in CH 3 COOH-CH 3 COONa buffer solvent. The absorbance was monitored at fixed time intervals with UV-vis spectroscopy. An impact typical of surfactants was observed on the ninhydrin–methionine reaction and explained by a pseudo-phase model of micelles. The effect of different temperatures (343 to 363 K) was also determined. Based on data showing the impact of temperature on k ψ , several relevant thermodynamic quantities, Δ H # , Δ S # , and E a , were calculated using linear least-squares regression. In addition, the influence of the other reaction ingredients on the reaction, that is, pH and the concentration of ninhydrin and methionine, was studied. The CMC (critical micelle concentration) of pure geminis and the surfactant system with methionine and ninhydrin was evaluated at two temperatures, i.e. at 303 K and 353 K by conductivity measurements. The CMC values of pure gemini surfactants evaluated in the existing case at 303 K are concordant with the results stated before. Moreover, other parameters, including rates and binding constants, were calculated.

“…In the presence or absence of aqueous environment, different amphiphilic substances such as surfactants (Seymour 1979 ; Molina-Bolivar et al 2001 , 2002 ; Ghasemi and Bagheri 2020 ; Bhattarai et al 2022 ; Alghamdi et al 2023 ; Ahmed et al 2022 ), drugs (Dutta et al 2022 ; Kumar et al 2022 ; Hasan et al 2022 ; Akter et al 2022 ), polymers (Khalil et al 2012 ; Lashkarbolooki et al 2020 ), etc. have ability to form self-aggregates, which are called micelles (aggregates).…”

Herein, interactions between cetylpyridinium chloride (CPC) and ceftriaxone sodium (CTS) were investigated applying conductivity technique. Impacts of the nature of additives (e.g. electrolytes or hydrotrope (HDT)), change of temperatures (from 298.15 to 323.15 K ), and concentration variation of CTS/additives were assessed on the micellization of CPC + CTS mixture. The conductometric analysis of critical micelle concentration (CMC) with respect to the concentration reveals that the CMC values were increased with the increase in CTS concentration. In terms of using different mediums, CMC did not differ much with the increase in electrolyte salt (NaCl, Na 2 SO 4 ) concentration, but increased significantly with the rise of HDT (NaBenz) amount. In the presence of electrolyte, CMC showed a gentle increment with temperature, while the HDT showed the opposite trend. Obtained result was further correlated with conventional thermodynamic relationship, where standard Gibb’s free energy change , change of enthalpy , and change of entropy ) were utilized to investigate. The values were negative for all the mixed systems studied indicating that the micellization process was spontaneous. Finally, the stability of micellization was studied by estimating the intrinsic enthalpy gain ( ) and compensation temperature ( T c ). Here, CPC + CTS mixed system showed more stability in Na 2 SO 4 medium than the NaCl, while in NaBenz exhibited the lowest stability.
