Sažetak
Anionic surfactants (ASs) are the most efficient group of surfactants so they are widely used in different types of industry. Because of their influence on ecosystem, it is of great importance to determinate even low concentrations of ASs in environmental samples. It is also very important to monitor ASs concentrations in industrial processes as well as in industrial effluents to prevent negative impact on the environment.Anionic surfactant selective electrode with dimethyldioctadecylammonium-tetraphenylborate (DDA-TPB) and carbon powder incorporated in liquid membrane is used for determination of ASs using potentiometric titration method. Twenty water samples grouped in four categories (effluents from households, food industry, detergent industry and surface water from river Drava near the wastewater discharge) are analysed. The sensor showed excellent selectivity, high sensitivity, thus enabling the accurate determination of very low ASs concentrations in complex systems as industry wastewaters. Savitzky-Golay method, developed by Barak, was used for reliable calculations of equivalence points from the titration curves with poorly defined inflexions, during determination of very low concentrations of ASs. Accuracy of determination was verified using reference method for ASs determination (Methylene blue active substances method, MBAS).
