Sažetak
Sequential Injection Analysis (SIA) was used in these investigations for determination of anionic surfactants (AS) in diluted detergent formulations, used as model effluents. A flow through home-made potentiometric detector, implemented into a home-made SIA system, recorded the electromotive force changes as a function of the AS concentration investigated. Sodium dodecyl sulfate and sodium dodecyl benzsulfonate were used for the calibration purpose. The specific software was developed for the data aquisition and elaboration, as well as for the instrument control. The detector exhibited almost Nernstian response toward the sufactants investigated down to 10^6 M. A 1, 3-didecyl-2-methylimidazolium-tetraphenylborate ion-pair was applied as electroactive material in the detector sensing element. The standard addition methodology was used for testing the method, whereas the potentiometric titration was used as a reference method.
