Abstract

Phosphorus nuclear magnetic resonance ((31)P-NMR) spectroscopy has advanced our knowledge of organic phosphorus (P) in soils and environmental samples more than any other technique. This paper reviews the use of (31)P-NMR spectroscopy for soil, water and other environmental samples. The requirements for a successful solid-state or solution (31)P-NMR experiment are described, including experimental set-up, sample preparation, extractants, experimental conditions, and post-experimental processing. Next, the literature on solid-state and solution (31)P-NMR spectroscopy in environmental samples is reviewed, including papers on: methods; P transformations; agricultural, forest and natural ecosystem soil studies; humic acid and particle size separations; manure, compost and sludge studies; and water research, including freshwater, estuary and marine studies. Future research needs are also discussed as well as suggestions to improve results, such as increased standardization among research groups.

摘要

磷核磁共振（³¹P-NMR）光谱技术比其他任何技术都更有助于我们了解土壤和环境样品中的有机磷（P）。本文综述了³¹P-NMR光谱技术在土壤、水和其他环境样品中的应用。描述了成功进行固态或溶液³¹P-NMR实验的要求，包括实验设置、样品制备、萃取剂、实验条件和实验后处理。接下来，综述了环境样品中固态和溶液³¹P-NMR光谱技术的文献，包括以下方面的论文：方法；磷的转化；农业、森林和自然生态系统土壤研究；腐殖酸和粒度分离；粪便、堆肥和污泥研究；以及水研究，包括淡水、河口和海洋研究。还讨论了未来的研究需求以及改进结果的建议，例如研究团队之间加强标准化。
