Development of an analytical method for white phosphorus (P₄) in water and sediment using solid-phase microextraction by Marianne E. Walsh Download PDF EPUB FB2

Headspace solid-phase microextraction (SPME) methods were developed for white phosphorus in water and sediment/soil to minimize waste generated by methods based on solvent extraction. Development of an analytical method for white phosphorus (P₄) in water and sediment using solid-phase microextraction.

Hanover, N.H.: US Army Corps of Engineers, Cold Regions Research & Engineering Laboratory ; Springfield, VA: NTIS [distributor], [] (OCoLC) Material Type. Rather, the intention is to identify well-established methods that are used as the standard methods of analysis.

Many of the analytical methods used for environmental samples are the methods approved by federal agencies and organizations such as EPA and the National Institute for Occupational Safety and Health (NIOSH).

Total reactive phosphorus is an ambiguous analytical measurement because the quantitative results depend strongly on color development time. For low level analysis, long path lengths have advantages in more precisely resolving low concentrations.

Chemistry of White Phosphorus WP is a transparent waxy solid. It darkens upon exposure to light and is highly reactive, igniting spontaneously in air at temperatures above 30 ‘C.

WP should be stored and transported submerged in water to ensure its stability. WP is the most reactive of the three allotropes of elemental phosphorus (white, red.

An eco-friendly method for indirect determining phosphorus and sulfur in animal feed by ion chromatography was proposed. Using this method, it was possible to digest mg of animal feed in a microwave system under oxygen pressure (20 bar) using only a diluted acid solution (2 mol L −1 HNO 3).The accuracy of the proposed method was evaluated by recovery tests, by analysis of reference Cited by: 8.

Analysis of Mixtures of White Phosphorus, Phosphorus Oxychloride, and Phosphorus Trichloride R. Keeler, C. Anderson, and D. Satriana Analytical Chemistry 26 (5),   Abstract A simplified method for the analysis of total P(TP), total dissolved P(TDP) and dissolved reactive P(DRP) in multiple water samples has been developed.

The reported modification utilizes a single digestion reagent and a single “mixed reagent” to eliminate neutralization, transfer and dilution steps normally required in total P by: Highlights We review the available methods for analyzing various forms of phosphorus.

Biological, chemical, molecular and microscopic phosphorus analysis methods are summarized. Principles, advantages and limitations of each technique are discussed.

It is the key elements necessary for the growth of plants and animals. It is the eleventh most abundant element on the surface of the earth and is most commonly found as phosphate1.

WATER EPA []. Method White phosphorus (P4) by solvent extraction and gas chromatography. The world's supplies of phosphorus were for nearly a century obtained by a method substantially identical with that of Scheele.

Scheele's raw material bone-ash, containing as it does from 34 to nearly 40 per cent, of P 2 O 5 and decomposed easily by sulphuric acid, is still the best which can be used. METHOD DETERMINATION OF PHOSPHORUS BY AUTOMATED COLORIMETRY SCOPE AND APPLICATION This method covers the determination of specified forms of phosphorus in drinking, ground, and surface waters, and domestic and industrial wastes.

The methods are based on reactions that are specific for the orthophosphate ion. Phosphorus monitoring at wastewater treatment plants is essential as phosphorus (as total phosphorus) is an important main constituent regulated in treatment plant effluents.

Recent trends are towards increasingly lower phosphorus limits, requiring reliable lower and lower phosphorus measurements. There is a long history of P analysis in dilute matrices; i.e., river and lake.

Digestion methods: Because phosphorus may occur in combination with organic matter, a digestion method to determine total phosphorus must be able to oxidize organic matter effectively to release phosphorus as orthophosphate.

Three digestion methods are given in P.B.3, 4, and 5. In this study, an improved standard addition method (ISAM) was developed for the determination of phosphorus in soil by ICP-OES based on the conventional standard addition method (CSAM) and calibration curve method (CCM). Certified standard soils were analyzed by the proposed ISAM method.

The values obtained by ISAM method agreed with the certified by: 1. SCIENTIFIC COMMUNICATION. Analysis of Phosphorus Compounds.

Zero the spectrophotometer using the 0 µmoles standard (reagent blank). Determine the absorbance of each of the five standards at nm. Determine the absorbance of each of the samples at nm.

Generate a calibration curve using the standards and determine the concentration of phosphorus in the samples. The methods are based on reactions that are specific for the orthophosphate ion. Thus, depending on the prescribed pretreatment of the sample, the various forms may be determined. Except for in-depth and detailed studies, the most commonly measured forms are phosphorus and dissolved phosphorus, and orthophosphate and dissolved orthophosphate.
