To study the impact of biological treatment techniques on perfluoroalkyl acids (PFAAs) emissions in municipal sewage, high-performance liquid chromatography-tandem mass spectrometry was combined with WAX extraction enrichment to analyze the content and distribution of 14 PFAAs in the influent and effluent of 10 municipal sewage treatment plants that adopted 3 biological treatment techniques including...
Three commercial electrodes, Ta-Ir/TiO 2 , Rh-Ir/TiO 2 , and PbO 2 /TiO 2 , were used as electrochemical anodes, and their performance was evaluated by the electrochemical oxidation of ammonia at neutral pH in a continuous electrochemical quadrangular reactor. Based on the cyclic voltammetry scans and volt-ampere relation analysis, in direct oxidation,...
