Sažetak
Anionic surfactants are used in detergent formulations for laundry, personal care products, household cleaning products and industry. Their wide applications lead to water pollution and thus endanger the flora and fauna. Due to a lack of standard methods for the determination of anionic surfactants, new sensors, which are less expensive and miniaturized, are being continuously developed for easier and wider use. A new screen-printed potentiometric microsensor (SPMS) for the determination of anionic surfactants (ASs) is based on the dimethyldioctadecylammonium-tetraphenylborate (DDA-TPB) ion pair as a sensing material. Sensor is accurate, inexpensive, simple and very sensitive. DDA-TPB was used for the end-point detection during the potentiometric titrations of low levels of ASs in wastewater. Solutions of cetylpyridinium chloride (CPC) concentrations down to 5•10^-5 M were used as a titrant. Standard addition method was used for checking the precision and accuracy of measurements, and it provided very satisfactory results with recoveries between 98.3 to 102.0 % in pure AS solutions and 99.0 to 114.5 % in wastewater. Standard spectrophotometric method Methylene Blue Active Substances (MBAS) was used as control for comparison of the results obtained with new sensor.
