as holding leaching technique

Specialty Leaching Methods TestAmerica Laboratories

Leaching is the partitioning of contaminants between a solid and liquid phase (assuming local equilibrium), coupled with the mass transport of the aqueous or dissolved constituents (aka leachate or eluate). The extent of leaching is dependent on the site, material properties (chemical, physical and biological) and the length of time involved.
