Simultaneous determination of cationic surfactants and nonionic surfactants by ion-association titration.
A simultaneous determination of cationic and nonionic surfactants has been developed using ion-association titration. Tetrabromophenolphthalein ethyl ester (TBPE) was used as an indicator. Benzalkonium reacted with TBPE to form a blue ion-associate in the organic phase. When tetrakis(4-fluorophenyl)borate was added dropwise to the solution, the color of the organic phase turned to yellow at the...
متن کاملElectrodeposition of anionic, cationic and nonionic surfactants and gold nanoparticles onto glassy carbon electrode for catechol detection
Three surfactants were selected to modify glassy carbon electrode including sodiumdodecylbenzenesulfonate, Tween 80 and cetyltrimethylammonium bromide. The obtained nano-Au/surfactant/GCEs were characterized with scanning electron microscopy and electrochemicaltechniques. Electrochemical behavior of catechol at the nano-Au/surfactant/GCE was thoroughlyinvestigated for mo...

15 صفحه اولMicroemulsions with Nonionic Surfactants and Mint Oil
A combination of electrical conductivity, dynamic viscosity, dynamic light scattering and small angle X-ray scattering methods was used to study the properties of the water + propylene glycol/mixed nonionic surfactants/ peppermint oil + ethanol U-type microemulsions which can be diluted with any amount of water. The surfactants were sucrose laurate and ethoxylated mono-di-glyceride. The mixing ...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
