Abstract

The surface tension of aqueous solutions of cationic (dodecylammonium and dodecylpyridinium chlorides) and anionic (sodium dodecylsulfate) surfactants was measured in the presence of polyacrylamide in the solution.  A synergistic effect of reducing the surface tension of mixed solutions of cationic surfactants, in the region of sufficiently high concentrations of mixed solutions of sodium dodecyl sulfate, with polyacrylamide in the range of molar ratios of the mixture components - n (Surfactants : PAA) = 1: 1; 1: 0.25 was established. The values ​​of the maximum adsorption, the values ​​of the area per molecule or associate of surfactants in the adsorption layer, as well as the standard Gibbs free energy of adsorption of surfactant - PAA associates are calculated. In accordance with Rosen's model, the composition of mixed adsorption layers at the solution-air interface is calculated, as well as the parameter of intermolecular interaction in adsorption layers between molecules, cationic and anionic ions surfactants and PAA. The values ​​of the critical micelle concentration (CMC) of individual surfactants in aqueous solutions exceed the CMC of the studied surfactants in the presence of PAA, which promotes micelle formation.

聚丙烯酰胺存在下,表面活性剂在水溶液中的表面张力和结合力
在聚丙烯酰胺存在的情况下,测定了阳离子(十二烷基铵和十二烷基吡啶氯化物)和阴离子(十二烷基硫酸钠)表面活性剂水溶液的表面张力。在十二烷基硫酸钠混合溶液浓度足够高的区域内,阳离子表面活性剂与聚丙烯酰胺的混合溶液的摩尔比在混合物组分- n(表面活性剂:PAA) = 1:1的范围内具有降低表面张力的协同效应;1:0 .25成立。计算了最大吸附量、表面活性剂在吸附层中每分子或伴生物的面积以及表面活性剂- PAA伴生物的标准吉布斯自由能。根据Rosen的模型,计算了溶液-空气界面混合吸附层的组成,以及吸附层中分子、阳离子、阴离子表面活性剂与PAA之间的分子间相互作用参数。PAA存在时,水溶液中单个表面活性剂的临界胶束浓度(CMC)超过所研究表面活性剂的临界胶束浓度,促进了胶束的形成。
