Biogenic phosphorus speciations in the sediments of an artificial river in the Haihe River Basin characterized with ~(31)P nuclear magnetic resonance spectroscopy(~(31)P-NMR)
Phosphorus(P) speciations in the sediments of Fuyang New River,located in the Haihe River Basin of eastern China,were detected by31 P nuclear magnetic resonance spectroscopy(~(31)P-NMR).Totally six P species were detected in Fuyang New river,including two inorganic P species(orthophosphate and pyrophosphate) and four OP species(phosphonates,orthophosphate monoesters,phospholipids and DNA).Biogenic phosphorus in the sediments of Fuyang New River included phosphonates(0.11%~1.57%),orthophosphate monoester(8.9...
1 引言(Introduction)
磷(P)是淡水生态系统中重要的营养元素(Cade-Menun et al.,2006).农业、工业和生活污水的过量排放导致水体中磷含量急剧增加,引起淡水生态系统富营养化频发,水质恶化,进而影响淡水生态系统健康(Carpenter,2008).针对湖库的磷形态特征及富营养问题的研究?
