Original Abstract

The aim of this work is the determination of two selected artificial sweeteners (saccharin, sucralose) in wastewater from wastewater treatment plant (WWTP) in the Czech Republic and the subsequent degradation of the thus obtained concentrations in model water using advanced oxidation processes. An analytical method for the determination of the artificial sweeteners in wastewater has been developed. On sampling, wastewater samples were treated with Solid Phase Extraction (SPE) and then evaluated by HPLC/MS (High Performance Liquid Chromatography). The concentrations of artificial sweeteners found in samples from WWTP were spiked to model water and then treated by three AOPs: O3 / UV, H2O2 / UV and O3 / H2O2 methods. For each of these methods, the efficiency of the degradation of sucralose and saccharin was investigated. From the evaluated data it was found that the most efficient way of AOP processes for the removal of artificial sweeteners from water is the O3 / H2O2 method, where the degradation efficiency was almost 100 %.
