Sažetak
Green chemistry is design of chemical products and processes that reduce or eliminate use or generation of hazardous substances [1]. Respecting the general principles of green chemistry [2, 3], they should be also applied in laboratories whenever possible. Even though that standard methods for ionic surfactants determination suffer from numerous matrix interferences and uses chloroform, they are still most used all over the world. Following the Green chemistry principles that it is better to prevent the generation of waste, and to avoid the use of harmful solvents, in the case of surfactant analysis we prefer potentiometric titrations. They are performed directly in water solution on highlyautomated instrument. In the presence of interferents accuracy can be achieved simply by adjusting the conditions according to the nature of the matrix. In the last twenty years, we have worked in our laboratories on the development of new methods and our own surfactant-sensitive ion- selective electrodes. We paid special attention to complex matrixes, and developed methods, for example, for the determination of anionic surfactants in products that also contain amphoteric surfactants, polycarboxylates, etc. In these studies, we presented the results of surfactant analysis in complex matrix products from the detergent market, containing interferents like amphoterics, polycarboxylates etc. We used new sensor developed, characterized and tested on model and real samples. Results were compared with self-made sensor previously used in commercial samples analysis and confirmed a high degree of agreement.
