Abstract:
Samples were analyzed for dissolved organic carbon and total nitrogen concentrations using the catalytic oxidation method followed by the non-dispersive infrared detection. Dissolved organic matter composition of these samples were analyzed using optical (absorbance analyses from 180 to 900nm at 5nm intervals) and fluorescence analyses (spectrofluorometric analyses at exitation wavelenght range from 230 to 450 nm at 2 nm range and emission wavelenght range from 240 to 600 nm at 5 nm resolution), stable isotope analyses (delta13C-DOC analysed by catalytic oxydation followed by solid-state non dispersive infrered detection and coupled with isotope-ratio mass spectrometry) and molecular analyses (analysed by thermally assisted hydrolysis methylation-gas chromatography-mass spectrometry method). Major ions were analyzed too using HPLC method. Absorbance indices (i.e. SUVA254, E2:E3 ratio and Sr) were measured with a absorbance spectrometry (Biochrom Ultrospec 3100 pro UV/Visible Spectrophotometer) for events from 18B1* to 18B5* and a Horiba Duetta for events from 19B1* to 19B4*. Fluorescence indices (i.e. Fluorescence Index and Beta:Alpha index) were measured with spectrofluorimetry using a Horiba Duetta (events from 19B1* to 19B4*).
