摘要：

Organic pollutants in water originating from industrial sources are a major problem. For their detection, the application of thin film polymer transducers is described. The reflectometric interference spectroscopy (RIFS) technique was used as a method of detection. Sampling is achieved by an FIA system which allows the determination of concentrations of hydrocarbons in water. The experimental set-up is outlined in detail. The sensitivities for toluene and different chlorinated hydrocarbons are given. The sensors used show a linear dependence on the analyte concentration over a wide concentration range. The limit of detection achieved with this system is discussed.
