Phosphorus compounds in sequential extracts of animal manures: chemical speciation and a novel fractionation procedure.
Pollution of water bodies by phosphorus in runoff from soil amended with animal manures is one of the greatest threats to water quality in developed countries. The environmental fate of manure phosphorus is determined in part by its chemical composition, yet extraction procedures to assess this are poorly developed and provide no structural information. We used solution 31P NMR spectroscopy to ...
متن کاملEnzymatic characterization of organic phosphorus in animal manure.
Information on the forms of P present in animal manure may improve our ability to manage manure P. In most investigations of manure P composition, only inorganic and total P are determined, and the difference between them is assigned as organic P. In this study, we explored the possibility of identifying and quantifying more specific organic P forms in animal manure with orthophosphate-releasin...
متن کاملCharacterization of organic phosphorus in lake sediments by sequential fractionation and enzymatic hydrolysis.
The role of sediment-bound organic phosphorus (Po) on lake eutrophication was studied using sequential extraction and enzymatic hydrolysis by collecting sediments from Dianchi Lake, China. Bioavailable Po species including labile monoester P, diester P, and phytate-like P were identified in the sequential extractions by H2O, NaHCO3, and NaOH. For the H2O-Po, 36.7% (average) was labile monoester...
متن کاملQuantitative analysis of phospholipids by 31P-NMR.
High-field 31P nuclear magnetic resonance spectroscopy was used to quantitate phospholipids in mixtures in organic solvents. The sample is dissolved in chloroform-methanol and analyzed at 161.7 MHz with decoupling of the protons. Signals were identified using authentic compounds, and their relative distribution was measured in mole percent. The method has good accuracy and reproducibility, and ...
متن کاملCharacterization of Phosphorus in Animal Manures Collected from Three (Dairy, Swine, and Broiler) Farms in China
In order to identify the phosphorus species and concentration in animal manure, we comparatively characterized phosphorus in dairy manure, swine manure, and broiler litter, using a sequential procedure, a simplified two-step procedure (NaHCO3/NaOH+EDTA), and a solution Phosphorus-31 Nuclear Magnetic Resonance (31P-NMR) spectroscopy procedure. In the sequential procedure, deionized water extract...
