Composition and cycling of natural organic matter: Insights from NMR spectroscopy
(Georgia Institute of Technology, 2005-11-28)Different aspects of natural organic matter composition and cycling have been studied using solid-state 13C and 31P Nuclear Magnetic Resonance (NMR) spectroscopy. Depending on the specific study, complementary analytical ... -
The distribution of charge and acidic functional groups in natural organic matter: the dependence on molecular weight and pH
(Georgia Institute of Technology, 2005-08-25)The Suwannee River natural organic matter (SRNOM) was fractionated by preparative size-exclusion chromatography (SEC) into seven molecular weight (MW) fractions. The SRNOM and its MW fractions were subsequently analyzed ... -
Natural Organic Matter: Isolation and Bioavailability
(Georgia Institute of Technology, 2007-04-09)Electrodialysis (ED) experiments were conducted on reverse osmosis (RO)-concentrated solutions of NOM from six rivers. The ED processes successfully recovered 88 11% of TOC, and removed 83% 19% of SO42- and 67% 18% of ...
