Organic phosphorus is an important component of soil biogeochemical cycles, but must be extracted from soil prior to analysis. Here we critically review the extraction of soil organic phosphorus, including procedures for quantification, speciation, and assessment of biological availability. Quantitative extraction conventionally requires strong acids and bases, which inevitably alter chemical structure...
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,...
A novel analytical technique has been suggested for determination of Pb using formation of PbH 4 (g) by chemical reduction and its subsequent spectrophotometric measurement in IR region, using the peak at 1821.4cm −1 . The range of measurements is 1.0–30.0mgl −1 using a sample of 1.0ml in flow injection mode. The 3σ limit of detection is 0.28mgl −1 . The method has...
