Soil Sample Preparation and Extraction
نویسنده
چکیده
In the Northeast, routine testing of soil samples invariably begins with a drying step and is followed by some form of pulverization. Analysis of dried, ground, sieved soils allows for more convenient sample handling and greater reproducibility of results in comparison with analysis of field-moist soil. Sample preparation steps, although often taken for granted, have frequently been shown to significantly affect analytical results (Elk and Gelderman, 1988; Munter, 1988; Soltanpour 1976).It is therefore critical that standardized sample handling and extraction procedures be used by soil testing laboratories.

Investigations of Sequential Extraction of Chromium from Soil
The sequential extraction of Cr from soil to soil eluates was studied. The influence of conditions of soil sample preparation and conditions of eluates obtained in the final result of Cr extraction from soil and its determination were found. Conditions protecting the total extraction of Cr from soil to solutions were
متن کاملComparison of Sample Preparation Methods for the Analysis of Volatile Organic Compounds in Soil Samples: Solvent Extraction vs Vapor Partitioning
Presently, both direct vapor partitioning and solvent extraction methods of sample preparation are commonly used for the characterization of volatile organic compounds (VOCs) in soil. These two approaches of recovering VOCs from this matrix, and other forms of solid waste, are often used interchangeably without any recognition of how different parameters (enviromental and procedural) influence ...
متن کاملEvaluation of thallium rate in soil after dispersive liquid-liquid micro-extraction
Thallium is widely found in nature, but the only inorganic stones full of this element are crookesite and lorandit. It isalso found in pyrites of copper, lead and inorganic stones. The element and its compositions are toxic and harmful to theenvironment; therefore, its application requires caution and further research. It is important to develop sensitive andaccurate analytical methods to deter...
متن کاملEffect of soil properties and sample preparation on extractable and soluble Pb and Cd fractions in soils
The effect of soil extraction procedures and/or sample pretreatment (drying, freezing of the soil sample) on the extractability of cadmium and lead was tested in a model experiment, with an employment of optical emission and atomic absorption spectrometry methods. In the first part, 6 extraction procedures were compared: 2 mol l HNO3, 0.43 mol l CH3COOH, 0.05 mol l EDTA, Mehlich III extraction ...
متن کاملApplications of liquid-phase microextraction in the sample preparation of environmental solid samples.
Solvent extraction remains one of the fundamental sample preparation techniques in the analysis of environmental solid samples, but organic solvents are toxic and environmentally harmful, therefore one of the possible greening directions is its miniaturization. The present review covers the relevant research from the field of application of microextraction to the sample preparation of environme...
