The interfacial properties of binary betaine and anionic surfactant mixtures at decane-water interface have been studied via molecular dynamics simulations. Two betaines chosen are alkyl sulfobetaine (ASB) and alkylbenzene sulfobetaine (BSB), while three

Herein, we have investigated the mixed micellar behavior of carboxylate anionic dimeric surfactants (CAD12 and CAD16) with commercial surfactants; anionic type i.e., sodium dodecyl sulfate, cationic i.e., cetyltrimethylammonium bromide and nonionic i.e., polyethylene glycol p-(1,1,3,3-tetramethylbutyl)-phenyl ether.

Journal of the American Oil Chemists' Society, 1963
ConclusionsA study of the sodium monoalkyl phosphates and sodium dialkyl phosphates has shown that the dialkyl esters, in general, possess markedly superior surfactant and detergent properties compared to the monoalkyl esters. This is true whether we are comparing equivalent mol wt mono‐ and diesters or when comparing those made from the same alcohols ...

Separation of anionic surfactants on anion exchangers
Journal of Chromatography A, 1995Abstract Two anion-exchange columns, PRP-X100 and IonPac AS11, that differ in anion-exchange capacity and porous properties are evaluated for applications in the separation of anionic surfactants such as alkane sulfonates, alkyl sulfates, and linear alkylbenzene sulfonates.

Adsorption of anionic surfactants onto sepiolite
Journal of Hazardous Materials, 2007Anionic surfactants constitute the main ingredients of detergents and a number of surfactant formulations used in a spectrum of diverse industries. The aim of this study is to examine the amenability of natural sepiolite to the adsorption of anionic surfactants, sodium dodecylsulfate (SDS) and sodium dodecylbenzenesulfonate (SDBS).

Interactions of anionic surfactants with methemoglobin
Colloids and Surfaces B: Biointerfaces, 2011Interactions of two anionic surfactants, sodium dodecyl sulphate (SDS) and sodium bis(2-ethylhexyl) sulfosuccinate (AOT) at concentrations below and above critical micelle concentration with methemoglobin (metHb) have been investigated by conventional as well as by stopped-flow absorption and fluorescence spectroscopy.

Anionic surfactant templated mesoporous silicas (AMSs)
Chem. Soc. Rev., 2013This tutorial review highlights the research on anionic surfactant templated mesoporous silica (AMS), which employs a co-structure directing agent (CSDA) to establish the critical interaction between the surfactant head group and silica species. As the geometry of anionic surfactants can be readily tuned via the ionisation of the surfactant head group,

Determination of Anionic Surfactants in Water
International Journal of Environmental Analytical Chemistry, 1971Abstract The use of ternary complexes in the determination of anionic surfactants has been investigated and an analytical method using linear alkyl sulfonates as a test substance has been developed. The method involves the formation of the chloroform-extractable bisphenanthroline Cu(II)-linear alkyl sulfonate (LAS) complex and the subsequent ...
