Thermodynamic studies of mixed ionic/nonionic surfactant systems.
Mixtures of alkyltrimethylammonium bromide (CnTAB, n=12, 14, 16, 18) and Triton X-100 were studied at a range of mole fractions of ionic surfactant per nonionic surfactant. For each mixture, the cmc obtained from surface tension measurements differed from that obtained using potentiometry. The behavior of these mixed-surfactant systems showed three different regions with increasing total surfac...
متن کاملEffect of nonionic surfactant additives on the performance of nanofluid in the heat exchanger
A nanofluid is mixture of nano sized particles and a base fluid. This paper investigates by using laboratory based double pipe heat exchanger model, the performance of nanofluid containing about 48.46nm particle size nanoparticles (ZnO) without or with addition of nonionic surfactant Rokanol K7 (500ppm) into the base fluid double distilled water to prepared three different concentrations 1.0%,...

متن کاملStudy of the Cloud Point of Nonionic Surfactant and Nonionic-cationic Surfactant Mixture: Effect of Electrolytes
Clouding phenomenon generally occurs with nonionic surfactants when the temperature of the system is raised to a certain value. This critical temperature is termed the cloud point (CP). The aqueous solutions of nonionic surfactants show complex phase behaviour including liquid-liquid phase separation at this temperature. The cloud point of aqueous surfactant solutions is influenced by the prese...
متن کاملsurvey on the rule of the due & hindering relying on the sheikh ansaris ideas
قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
