“…Gemini surfactants can be 10 to 100 times more surface active than conventional ones and, hence, are gaining wide attention in both academic and industrial research [20,21]. These surfactants have shown great promise in skin care [22], drug entrapment and release [23], gene therapy [24] and antibacterial regimens [25] as well as in various analytical processes [26].…”

Amitriptyline Hydrochloride / Zwitterionic Gemini Surfactants / Surface Tension / Mixed MicellesThe physicochemical properties, viz, critical micelle concentration (cmc), surface excess concentration (Γ max ), minimum area per head group ( A min ) of zwitterionic surfactants (designated as n(−)-2-m(+); n = 8, 10, 12 and m = 12, 14, 16) and their mixtures with amphiphilic antidepressant drug amitriptyline hydrochloride (AMT) were determined by using surface tension measurements. The cmc and ideal cmc (cmc id ) values along with interaction parameters, β m and β σ (calculated using Rubingh's and Rosen's models), suggest attractive interactions among the components. The Krafft temperature measurements also indicate strong attractive interactions. Γ max (or A min ) increases (or decreases) with the addition of gemini surfactant; the values being closer to that of the drug. These values and micellar mole fraction (X m 1 -calculated from Rubingh's model and X Moto 1 -calculated from Motomura's model) indicate larger contribution of gemini surfactants in mixed micelles and smaller contribution at air/solution interface (as mole fraction values at interface, X σ 1 , are slightly smaller than X m 1 ). The standard Gibbs energy of micellization (ΔG • mic ) and adsorption (ΔG • ad ) as well as excess energy of mixing (ΔG m ex ) are all negative. All these results suggest higher stability of the mixed systems. UV absorbance results also suggest that the mixed micelles are stable for several days.

“…A similar explanation was reported in the previous article (Chen et al, ). For anionic/nonionic surfactant mixtures, the head groups of the anionic surfactant were surrounded by the ethylene oxide chain of the nonionic surfactant, which weakens the mutual exclusion of the headgroup‐headgroup of anionic surfactants and promotes the dipole attraction between different head groups (Hu et al, ; Zhou and Rosen, ). As a result, the mixing micelles are relatively easy to form.…”

As a class of novel surfactants, Gemini surfactants usually exhibit fairly excellent interfacial properties in aqueous solutions on account of the unique structure. They have significant application and development potential for industrial production. However, the mixing properties of Gemini surfactants with conventional surfactants are the key to their application. The equilibrium surface tension curves of anionic/nonionic surfactant mixtures based on the sulfonate Gemini surfactant (SGS‐12) were measured using the Wilhelmy Plate method. The parameters of surface adsorption, the interaction parameters between anionic and nonionic surfactants, and the thermodynamic parameters of micelle formation were calculated from the corresponding equations. In addition, the dynamic surface tension (DST) curves of anionic/nonionic surfactant mixtures were examined through bubble profile analysis, and the diffusion performance parameters were acquired from empirical formulas. The solubilization of pyrene in micelle solutions was studied using UV–vis absorption spectroscopy. The results show that the interaction parameters of all anionic/nonionic surfactants are negative, indicating that there is a synergistic effect on reducing the surface tension. For the SGS‐12/OP‐10, SGS‐12/Tween 80, SGS‐12/AEO9, and SGS‐12/APG0810 mixtures, the optimum mixing ratios are 6:4, 7:3, 7:3, and 8:2, respectively. The thermodynamic data of micelles show that the formation of mixed micelles for SGS‐12/APG0810 mixtures is an enthalpy‐driven process. The tendency of DST curves of the SGS‐12/APG0810 mixture is similar to that of SGS‐12. In comparison with single‐surfactant solutions, the anionic/nonionic surfactant mixtures show stronger solubilization capacity toward pyrene.

“…In addition, the strong effect between two head groups of Gemini surfactant and aromatic organics and the stability micelles could elevate their solubilization power. As a consequence, all above efforts could excites the shape of micelles, the promotion of the size of micelles, and the aggregation number [37,38], thus more phenol would be dissolved in micelles and can be observed from the higher D and P m values in the Fig. 2.…”

A systematic study has been conducted to have an insight into the separation efficiency of phenol with the help of Gemini surfactants and conventional nonionic surfactant in their single and mixed systems using micellar-enhanced ultrafiltration (MEUF). A flat sheet membrane with a total effective area of 0.08 m 2 and a molecular weight cut-off of 10 kDa, was selected in this investigate. The effects of feed component (surfactant concentration for single surfactant system and mixed ratio for mixed surfactant system) on solubilization and filtration efficiency were researched. Some related parameters were used to estimate the performance of various surfactant systems, such as distribution coefficient (D), the phenol concentration in micellar phase (P m ), the surfactant concentration in micellar phase (S m ), the micelle loading (L m ), and the equilibrium distribution constant (K). With the increase of feed surfactant concentration or the addition of nonionic surfactant, the degree of solubilization of phenol enhances, leading to the decrease of permeate concentration and the augment of retentate concentration. Consequently, D, P m , and S m increases. The addition of nonionic surfactant has positive effects to recounterbalance the interior structure and improve the micellar solubilization power for phenol. Both the single and mixed C 12-2-16 systems have higher D, P m , and S m values than these of C 12-2-12 , due to the longer length alkyl chain and more optimized structure. L m and K are the significant indicators for evaluating the effectiveness of dissolving phenol. Irreversible fouling was almost eliminated with a series of cleaning solution in a short time. There results from the laboratory-scale experiments could be very useful in selection of the suitable surfactant systems for raising efficiency and could serve as valuable guide for MEUF in industrial application.
