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 کاملInteractions of β-lactoglobulin with Cationic Surfactants: Spectroscopy Study
The interactions of β-lactoglobulin AB in the presence of cationic surfactants such as Cetyltrimethylammonium bromide and Cetyltrimethylammonium p-Toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, UV-Vis spectrophotometry and fluorimetry. The conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...
متن کاملApplication of membrane filters for spectrophotometric determination of cationic surfactants in river water and sediment.
Cationic surfactant (CS+) in urban river water and sediment was extracted and determined spectrophotometrically with 2 membrane filters. The CS+ in the water samples, mostly in the form of an ion associate with the coexisting anionic surfactant (AS), was collected on a polytetrafluoroethylene (PTFE) membrane filter and eluted with methanol. Bromphenol blue (BPB), hydrochloric acid, and water we...
متن کاملSemi-quantitative determination of cationic surfactants in aqueous solutions using gold nanoparticles as reporter probes.
Concentrations of cationic surfactants in aqueous solutions have been estimated on the basis of changes in the color of gold nanoparticles, used as reporter probes. We have shown that the colors of gold nanoparticles with anionic protective groups on their surfaces shift from red to indigo/purple and then back to red in a range of cationic surfactant solutions in which concentrations vary from ...
متن کاملSimultaneous Separation of Anionic, Nonionic, Cationic and Amphoteric Surfactants Using a Single HPLC Column
High performance liquid chromatography (HPLC) is the preferred analytical technique for the separation and identification of surfactants in consumer products. Although many HPLC columns are available for surfactant analysis, none of these columns provide optimal selectivity for the analysis of anionic, nonionic, cationic, and amphoteric surfactants. This article describes an HPLC column, Acclai...
