Sonolysis of aqueous solutions of n-alkyl anionic surfactants results in the formation of secondary carbon-centered radicals (-*CH-). The yield of -*CH- depends on the bulk surfactant concentration up to a maximum attainable radical yield (the 'plateau yield') where an increasing

Sonolysis of argon-saturated aqueous solutions of the nonvolatile surfactants sodium dodecyl sulfate (SDS) and sodium 1-pentanesulfonate (SPSo) was investigated at three ultrasonic frequencies under both continuous wave (CW) and pulsed ultrasound. Secondary carbon-centered radicals were detected by spin trapping using
A simple and selective micellar electrokinetic chromatography (MEKC) with UV detection is described for simultaneous determination of amikacin, tobramycin, and kanamycin A, performed in Tris buffer (180 mM; pH 9.1) with 300 mM sodium pentanesulfonate (SPS) as an anionic surfactant.

The five active drug substances and two of the excipients present in Frenadol, a cold medication, were separated. The active drug components dextromethorphan HBr monohydrate, ascorbic acid, caffeine, paracetamol and chlorpheniramine maleate were quantitatively assayed by a mixed ion pair
Journal of colloid and interface science, 346(1), 107-117 (2010-03-24)
Thermodynamic properties for aqueous solutions containing sodium pentane-1-sulfonate (C(5)SO(3)Na) in the absence and presence of poly(ethyleneglycol) (PEG) or poly(vinylpyrrolidone) (PVP) determined as a function of surfactant concentration from the density, sound velocity, viscosity, conductivity and vapor-liquid equilibria data, are reported
