Anionic surfactant selective electrode for the titrimetric determination of anionic surfactant
Russian Journal of Electrochemistry, 2012The 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 ...

Anionic surfactants: lauric products
Journal of the American Oil Chemists' Society, 1985AbstractLauryl sulfate and lauryl ether sulfate obtained by the sulfation of lauryl alcohol and lauryl alcohol ethoxylate are representative of anionic surfactants and are used as a formable detergent or an emulsifier. For the sulfation of lauryl alcohol and lauryl alcohol ethoxylate, SO3 gas, it was found that the quality of products was significantly
