Sažetak
Anionic surfactants are the most significant type of surfactants, commercially. The standard reference methods for their determination are methylene blue active substances method (MBAS) and two-phase titration. Although these methods are frequently applied, they suffer from many drowbacks such as lack of ability to be automated and miniaturized and use of toxic and carcinogenic organic solvents. Due to the fact that it is necessary to monitor anionic surfactants concentration in environment, as well as in industrial processes and products, there is a need to improve existing sensors and methods for their determination. A new liquid membrane type of anionic surfactant selective electrode based on tetraoctadecylammonium-tetraphenylborate (TODA-TPB) is constructed. Three electrodes with different percentage of electroactive material (1%, 3% and 5%) are compared. The best response characteristics and the highest jump in equivalence point during potentiometric titration of anionic surfactants exhibited electrode with 3% of electroactive material so that electrode is selected for further characterization. The selected sensor exhibits a Nernstian response for analyzed anionic surfactants (sodium dodecyl sulfate and sodium dodecylbenzenesulfonate) and excellent selectivity performance. The applicability of the sensor is demonstrated by succesfull determination of anionic surfactants in real samples (commercial detergents and effluents).
