Sažetak
Green analytical methods1 for anionic, cationic and non-ionic surfactants determination are presented. In all determination home-made liquid membrane potentiometric sensors as indicator electrodes and potentiometric titrator of high sensitivity and precision were used. Potentiometric titration were performed in an aqueous sample solution2, 3 (e.g., detergents, washing and cleaning agents, etc.) or directly (wastewater samples4 ) without any pretreatment. Due to the flexibility of this analytical technique, it provides the possibility of adjusting the determination conditions (e.g., adjusting the pH value of the analytical solution) with the aim of removing the influence of interferents (e.g., polycarboxylates, betaines, amine-oxides, soaps, etc.) on the accuracy of the determination. Furthermore, these methods have a whole series of other properties that make them interesting for expanding the field of their application. Besides the fact that these methods belong to green methods, and enable the quantitative determination of surfactants, they also provide monitoring of their behavior in complex matrices that are very common in reality. Generally, these electroanalytical methods are green methods for determination of anionic, cationic and non-ionic surfactants in real samples3 and waste waters, 4 and alternative for standard methods used. Despite the fact that standard methods5, 6 use harmful organic solvents (e.g., chloroform) and are environmentally unacceptable as a green method, they are still the most prevalent in practice today.
