有机废弃物的磷素形态研究进展

Advance in the Characterization of Phosphorus in Organic Wastes

有机废弃物磷形态研究是开展环境风险评价和合理施用有机肥的重要基础。回顾了有机废弃物的种类,分析了影响有机废弃物磷素形态的主要因素,重点介绍和评述了有机废弃物的磷素形态分析方法,主要包括总磷、水溶解态磷(WEP)、物理化学法、连续化学提取法、酶水解法、核磁共振(NMR)技术、同步辐射X射线近边能谱技术(XANES)等。

Researching on organic waste phosphorus forms is the important base of environmental risk assessment and rational application of organic wastes. In this paper, various types of organic wastes and factors affecting P composition in organic wastes from production to land disposal were reviewed. Then, the various methods that have been used to characterize P forms, including total P, water extractable P （WEP）, physicoehemical fractionation, sequential chemical fraetionation, enzymatic hydrolysis, nuclear magnetic resonance （NMR）, and x-ray absorption near edge structure （XANES） spectroscopy were introduced and evaluated.
