SURFACTANT SENSOR BASED ON 1,3-DIHEXADECYL- 1HBENZO[D]IMIDAZOL-3-IUM FOR ANIONIC SURFACTANTS IN INDUSTRIAL WASTEWATERS

Anionic surfactants, or anionic surface active agents, are a group of surfactants usually used for washing and cleaning in household and industry. The population growth and rapid industrialization resulted in increased demands for anionic surfactant. Consequently, this resulted in water pollution with negative environmental and health impact. For this reason, there is a need to develop rapid and reliable analytical tools - surfactants sensors, for anionic surfactant monitoring. We developed a surfactant sensor, based on the 1, 3-dihexadecyl- 1Hbenzo[d]imidazol-3-ium-tetraphenylborate ionophore incorporated in the PVC liquid membrane, for anionic surfactants in wastewaters. The sensor was characterized and used for measurement of anionic surfactants in ten real samples of industrial wastewaters. The results were compared with the referent analytical method and showed good agreement.
