Quantification of Metal Leaching in Immobilized Metal Affinity

Nitrogen leaching following clear-cutting and soil scarification

To remove soluble or other constituents from by the action of a percolating liquid: heavy rains that leached the soil of minerals. Leaching is a mass transfer process which takes place through the extraction of a substance from a solid material that has come into contact with the liquid. Leaching is the normal mechanism by which water-soluble compounds from soil or waste are washed out. Such leached-out contaminants affect surface and subsurface water contamination. Leaching is actually two important actions occurring simultaneously: (1) chemical interactions with surfaces and (2) physical movement of water.

The separation usually involves selective dissolving, with or without diffusion, but in the extreme case of simple washing it consists merely of the displacement (with some mixing) of one interstitial liquid by another with which it is miscible.

Leaching is actually two important actions occurring simultaneously: (1) chemical interactions with surfaces and (2) physical movement of water. As the water passes through the rock and soil, it interacts with the surfaces of the materials.

leaching - Wiktionary

Nitrate leaching is also a signiﬁcant source of soil acidiﬁcation. In humid climates, some nutrient leaching occurs even under natural vegetation, but agricultural activities can greatly increase leaching losses (Havlin et al., 1999). Soil and climatic factors that inﬂuence nutrient leaching Leaching. The removal of a soluble fraction, in the form of a solution, from an insoluble, permeable solid with which it is associated.

The extraction of oils from peanuts, soybeans, sunflower seeds, cotton seeds, and halibut livers. In pharmaceutical industry, many products are obtained by leaching plant roots, leaves, and stems. In the metals processing industry leaching. the process of dissolving and removing nutrients from soil, or minerals from rock, by the percolation of water. Certain bacteria are able to help in the solubilization of metals from their ores; such bacterial leaching is carried out commercially to recover metals such as copper and uranium.

tr. 1. To remove soluble or other constituents from by the action of a percolating liquid: heavy rains that leached the leaching [ lē ′chĭng ] The removal of soluble material from a substance, such as soil or rock, through the percolation of water. Organic matter is typically removed from a soil horizon and soluble metals or salts from a rock by leaching. When a chemical substance leaches or is leached from a material, especially soil, it is removed by the action of water passing through the material: The calcium, potassium, and magnesium ions are leached or washed out of the top soil into lower inaccessible subsoil. Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.
