Construction of surfactant-membrane electrodes selective for sodium dodecyl sulfate in poly(ethylene oxide)-surfactant mixtures
Surfactant-selective electrodes to sodium dodecyl sulfate (SDS) monomer and bromide were constructed, respectively, electrode idicator and reference electrode. The electrodes were tested for solutions of SDS and in mixture of SDS and poly(ethylene oxide) (PEO). The profiles obtained measuring the potential (E) versus SDS concentration in the presence of 0.5% PEO are sensitive to polymer-surfactant parameters such as the onset of cooperative association of SDS to PEO, the critical aggregation concentration (cac), and the polymer saturation by SDS monomers (psp). The obtained parameters are in agreement with those values found by surface tension and electrical conductivity.
