The interaction of an anionic gemini surfactant with conventional anionic surfactants

Journal of Colloid and Interface Science, 2003
The interaction in two mixtures of an anionic gemini surfactant having N ,N -dialkylamide and carboxylate groups in a molecule, (CH2)2[N(COC11H23)CH(CO2H)CH2(CO2H)]2. 2NaOH (GA), and conventional anionic surfactants have been investigated in 0.1 M NaCl at pH 5.0.

Polymer chip incorporated with anionic surfactant-ISFET for microflow analysis of anionic surfactants

Sensors and Actuators B: Chemical, 2005
Abstract An anionic surfactant ion-sensitive field-effect transistor (anionic surfactant-FET) based on a hydrophobic quaternary ammonium salt, tetrahexadecylammonium bromide was developed. The anionic surfactant-FET shows an almost Nernstian response to sodium dodecylbenzenesulfonate (NaDBS) ion in the concentration range from 1.0 × 10 −6 to 1.0 ...

Determination of Anionic Surfactants in Water

International Journal of Environmental Analytical Chemistry, 1971
Abstract 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 ...

Anionic surfactant selective electrode for the titrimetric determination of anionic surfactant

Russian Journal of Electrochemistry, 2012
The construction and characteristic performance of a PVC membrane electrode responsive for sodium dodecylsulfate (SDS) are described in this paper. The electrode based on CTA+DS− ion pair as ionophore in PVC membrane displays a Nernstian slope of −58.8 ± 0.7 mV/decade in a 1.32 × 10−6 to 3.75 × 10−3 mol L−1 concentration range and a limit of detection ...

Interactions of anionic surfactants with methemoglobin

Colloids and Surfaces B: Biointerfaces, 2011
Interactions 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.
