“…Provenzano and co -workers have used DSC extensively to explore thermograms of soil, sediment, and aquatic organic matter and their fractions, relating the observed patterns to sample nature (i.e., composition) and their origin Senesi, 1998, 1999 ;Provenzano et al, 2006 ).

“…For example, the HoA fraction is often collected in one beaker when eluted from the XAD-8 column, and subsequently analyzed as a whole. In such a way, the HoA can only be characterized in bulk without being able to measure the potential presence of sub-fractions that contribute to the characteristics of bulk HoA (Provenzano et al 2006;Wong et al 2002). To date, only a few studies have focused on the further isolation of sub-fractions within the traditional primary chemical fraction (TPCF).…”

Conventionally, resin fractionation (RF) method has been widely used to characterize dissolved organic matter (DOM) found in different source waters based on general and broad DOM fractions grouping. In this study, a new refined method using multistep, microvolume resin fractionation combined with excitation emission matrix fluorescence spectroscopy (MSM-RF-EEMS) was developed for further isolation and characterization of subfractions within the primary DOM fractions separated from using the conventional RF method. Subsequently, its feasibility in indicating the occurrence of urban pollution in source waters was also assessed. Results from using the new MSM-RF-EEMS method strongly illustrated that several organic subfractions still exist within the regarded primary pure hydrophobic acid (HoA) fraction including the humic- and fulvic-like organic matters, tryptophan- and tyrosine-like proteins. It was found that by using the MSM-RF-EEMS method, the organic subfractions present within the primary DOM fraction could be easily identified and characterized. Further validation on the HoA fraction using the MSM-RF-EEMS method revealed that the constant association of EEM peak T1 (tryptophan) fraction could specifically be used to indicate the occurrence of urban pollution in source water. The correlation analysis on the presence of EEM peak T2 (tyrosine) fraction could be used as a supplementary proof to further verify the presence of urban pollution in source waters. These findings on using the presence of EEM peaks T1 and T2 within the primary HoA fraction would be significant and useful for developing a sensory device for online water quality monitoring.
