Spectrophotometric Determination of Anionic Surfactants in River Water with Cationic AZO Dye by Solvent Extraction- Flow Injection Analysis [PDF]
, 1987 Anionic surfactants in water were determined by a spectrophotometric flow injection technique coupled with solvent extraction. The ion associate which formed between an anionic surfactant and an cationic azo dye was extracted into an organic solvent and ...

Computational studies on the behaviour of anionic and nonionic surfactants at the SiO$_{2}$ (silicon dioxide)/water interface [PDF]
, 2016 Molecular dynamics simulations to study the behaviour of anionic (Sodium Dodecylsulfate, SDS) and nonionic (Monooleate of Sorbitan, SPAN80) surfactants close to a SiO$_{2}$ (silicon dioxide) surface were carried out. Simulations showed that a water layer

An HLD framework for cationic ammonium surfactants
JCIS Open, 2021 The Hydrophilic-Lipophilic Difference (HLD) model can be described by additive contributions accounting for the effect of the oil and surfactant nature, temperature, ionic strength, and so on.

Nanocarrier lipid composition modulates the impact of pulmonary surfactant protein B (SP-B) on cellular delivery of siRNA [PDF]
, 2019 Two decades since the discovery of the RNA interference (RNAi) pathway, we are now witnessing the approval of the first RNAi-based treatments with small interfering RNA (siRNA) drugs. Nevertheless, the widespread use of siRNA is limited by various extra-

Study of Foaming Properties and Effect of the Isomeric Distribution of Some Anionic Surfactants [PDF]
, 2008 Using different reaction conditions of photosulfochlorination of n-dodecane, two samples of anionic surfactants of sulfonate type are obtained. Their micellar behavior has been already reported and the relationship between their isomeric distribution and

Aqueous Properties of Mixed Anionic Gemini Surfactant and Conventional Anionic Surfactant
Journal of Oleo Science, 2002 In order to determine the characteristics of a mixed system of an anionic gemini surfactant with N, N-dialkylamide and carboxylate groups and a conventional anionic surfactant, aqueous solutions of (CH2)2[NCO(C11H23)C2H4CO2Na]2 (212)/sodium dodecanoate (soap) mixture were studied.
