Sažetak
Sequential Injection Analysis (SIA) was employed in the investigations reported for determination of anionic surfactants (AS) in the solution of detergent formulations. A potentiometric flow through self-made sensor was used as a detector using 1, 3-didecyl-2-methylimidazolium-tetraphenylborate ion-pair as a sensing material. The solutions of sodium dodecyl sulfate and sodium dodecylbenzensulfonate were used for the calibration of the system. The detector responded linearly to the logarithmic changes of the surfactant ion activities with the detection limit below 1 µM of AS investigated. Sample and reagent injection as the initial input parameters were investigated and optimized. A particular attention was paid to the selection of the carrier, controlling of dispersion process as well as to the reproducible timing. The standard addition method was used for testing the accuracy of the SIA determination, whereas the potentiometric titration was used as a reference one.
