Micellar Weights of and Solubilization of Benzene by a Series of Tetradecylammonium Bromides. The Effect of the Size of the Charged Head^1a

An investigation of the aggregation and water-air interfacial behaviour of a cationic tentacle molecule

“…In this instance we have assumed the coefficient a = 2 for a 1 : 1 electrolyte like DDPB, and a = 4 for a 3:1 electrolyte like (3). The value of A for DDPB at its c.m.c, is N 50 A 2, which is in agreement with our own value for dodecyl trimethyl ammonium bromide [10], itself in good agreement with data in the literature [17]. The tentative values for A derived from the plot for (3) at the approach to Yl, Y2, and Y3, respectively are -330, 360 and 240 A 2.…”

Adsorption and Association in Aqueous Solutions of Dissymmetric Gemini Surfactant

“…The cmc values obtained from both surface tension and conductivity measurements were in good agreement (Table 2) ammonium bromide, DTAB, and tetradecyltrimethylammonium bromide, TDAB (35,36), are also listed in Table 2. In comparison with geminis, the single-charged surfactants have much higher cmc values.…”

Surfactant-enhanced remediation of organic contaminated soil and water

“…The solubilization of organic contaminants by single surfactants has been studied extensively [2,68,103,120,135,136,[139][140][141][142][143][144][145][146][147][148][149][150][151][152][153][154][155][156][157][158], in compare to that, there are less study on mixed surfactant system [105,[159][160][161][162][163][164][165][166]. The MSR and K mw values of different organic contaminants in different surfactant solutions are shown in Table 8.…”
