Increases in PA (or PB) concentration, PMS dose and pH favored the rapid dye degradation. Gas chromatograph-mass spectrometer (GC-MS) data confirmed AO7 and 2,4,6-trichlorophenol (2,4,6-TCP) were decomposed to a series of organic intermediates. The radical quenching and probe oxidation experiments indicate the degradation of organic compounds in the PA/PMS and PB/PMS processes was not reliant on sulfate radical (SO₄•−) and hydroxyl radical (•OH) species but on O₂•− and ¹O₂ reactive species. Comparison experiments show that the polyphosphate/PMS process was much more favorable than PDS/base process. The present work provides a novel way to activate PMS for contaminant removal using industrial polyphosphate wastewaters.]]> Wed 13 Mar 2019 13:19:26 AEDT ]]> Peroxymonosulfate/base process in saline wastewater treatment: The fight between alkalinity and chloride ions https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47409 Tue 17 Jan 2023 16:29:29 AEDT ]]>
