Organic phosphorus compounds in the hydrosphere: Characteristics, identity and dynamics. Final report
Technical Report
·
OSTI ID:6590288
Identification and characterization of dissolved organic phosphorus (DOP) present in the waters of Crystal Lake in Urbana, IL, and Walker Branch at Oak Ridge, TN using ultrafiltration (UF) and reverse osmosis (RO) concentration methods, high performance liquid chromatography (HPLC), and Phosphorus-31 Fourier Transform Nuclear Magnetic Resonance spectroscopy (31P FT-NMR) is reported. UF and RO membrane methods enabled a several thousand fold concentration of the DOP, which was necessary for detection by HPLC and 31P FT-NMR. The behavior and recovery of aquatic DOP compounds with several UF and RO membranes were examined and a membrane configuration consisting of a 30 K dalton UF membrane, a 1 K dalton UF membrane, and a RO 95 percent NaCl rejection membrane, in series, was used to concentrate and fractionate DOP according to its molecular size. Extensive concentration with UF and RO membrane methods appear to produce aggregation of dissolved organic carbon compounds with the concurrent adsorption or incorporation of DOP.
