dc.description.abstractRecently UV/TiO2 photocatalytic treatment for municipal reverse osmosis concentrate (ROC) has drawn increasing attention due to its high efficiency and low cost. We determined the organics in ROC samples by a combination of multiple analytical techniques: i.e. electrospray ionization-quadrupole time of flight (ESI-QToF), photocatalytic degradation method, total organic carbon (TOC) analysis, fluorescence spectroscopy, ultraviolet-visible (UV-Vis) spectroscopy and gas chromatography/mass spectrometry (GC/MS). By these multiple techniques we were able to determine the total dissolved organic carbon (DOC) to be 24.50ppm, which was composed of high molecular weight (MW) (>2000Da) natural organic matter (NOM) of 23.36ppm (95.35%wt.) and low MW (
