Abstract

Dissolved organic matter (DOM) in petrochemical reverse osmosis concentrate (ROC) is important for developing ROC advanced oxidation techniques. In this studty, DOM before and after ozonation was fractionated using resin adsorbents into five classes: hydrophobic bases (HoB), hydrophobic acids (HoA), weakly hydrophobic acids (WHoA), hydrophobic neutrals (HoN) and hydrophilic matter (HiM). Hydrophobic organics dominate in DOM, in which HoN and HoA account for 29.2% and 19.5%, respectively. Ozone significantly decreases the percentage of HoN, while increases the concentration of WHoA and HiM. The UV-Vis analysis shows that ozonation decreases the molecular weight of DOM. In view of FTIR analysis, the unsaturated groups and aliphatic structurs are destroyed greatly and converted to more C-O structures, which shows relatively high hydrophilicity and low molecular weight. Through the analysis of fluorescence spectroscopy, it is found that ozone decreases significantly the fluorescence intensity of humic-like and fulvic-like substances in DOM, while increases the fluorescence intensity of soluble microbial products.
