Utilizing Phosphorus(I) Methods Towards Phosphorus(III) Heterocycles and Phosphorus(I) Macromolecules
… with it, as well as the chemistry of the atom. Phosphorus can exhibit a range of oxidation states such as; +1, +3, and +5. One of the main focuses of my research is to utilize phosphorus in the electron-rich +1 oxidation state to produce neutral P(I)-containing complexes that are analogous to …

Phosphorus Management: An Analysis of the Virginia Phosphorus Index
Excess phosphorus (P) that is transported into water bodies can cause water quality problems. A high potential for P delivery occurs when there is a high transport potential from erosion, runoff, and/or leaching coupled with high soil test P and/or high rate of fertilizer P application. A …

Relationships of soil test phosphorus with soil properties and phosphorus forms
… the key objectives of the present investigation. Phosphorus extracted by the four widely used soil extractants, i.e., Bray 1, Mehlich 1, Mehlich 3, and Olsen, represented less than 25 percent of the total P content in 43 Virginia soils from the Coastal Plain, Piedmont, and Ridge and Valley …

Removing Soluble Phosphorus from Tertiary Municipal Wastewater Using Phosphorus- Deprived, Filamentous Microalgae
… human health, and economies. The low levels of phosphorus remaining in the effluent of municipal wastewater treatment plants can contribute to HAB formation. To achieve more complete phosphorus removal, an effluent treatment method has been proposed that uses phosphorus-deprived, filamentous …

Phosphorus cycling in organic systems
Soil phosphorus (P) is often unavailable in SK soils due to immobilization by microbial biomass and complexation with cations. The prohibition of synthetic fertilizer use in organic systems means farmers rely on crop rotation or approved inputs to supply P for crops. Legumes in crop rotation add P …

Some investigations of phosphorus ylides
N-(o-aminophenyl)-iminotriphenylphosphorane (I) has been synthesised and its physical and chemical properties studied in depth, especially in its nucleophilic reactions.

Phosphorus Pathways In Deep Time
… science, geochemistry, and biology. The element phosphorus (P) is limiting for life in many environments on the modern Earth. Changes in global P availability may have played a large role in shaping biogeochemical evolution. Moreover, the baseline availability of P in planetary crusts is …

Phosphorus readsorption on Occoquan sediments
… investigation was to determine the extent of phosphorus readsorption on Occoquan sediments and the amount of subsequent removal because of settling of the particles with time. Occoquan sediments were placed in six polyurethane cylinders and submerged. In two separate experiments, the cylinders …
