Sažetak
Surfactants are used in almost all branches of industry and everyday life as home and industrial detergents, in cosmetics, pharmaceuticals, foods, crop protection etc. Their waste belongs to the most widespread organic pollutants, representing a global environmental problem, giving thus a great importance for their monitoring in environment. The existing methodology for the monitoring of anionic and nonionic surfactants in effluents is based on the time-consuming extraction-spectrophotometric procedures connected with numerous drawbacks: considerable chemicals consumption, use and disposal of toxic organic solvents etc. Potentiometric methods with surfactant sensors (surfactant-selective electrodes) sensitive to the surfactants overcome almost all of these disadvantages offering an attractive alternative to the existing methods. The biggest challenge in surfactant analysis is the determination of low levels in environmental samples. This paper outlines the principles of response mechanisms of these sensors and their application for the determination of anionic and nonionic surfactants in surface waters and effluents.
