The Toxicity Characteristic Leaching Procedure (TCLP) US EPA Method 1311, is intended to replicate the leaching of selected metals and organic compounds from materials placed into municipal landfills. If the extracted sample does not fail any of tha analytes listed in the TCLP test, the material may be placed into a municipal landfill for disposal.
For the determination of metals, the procedure uses an extraction fluid that is selected based on the initial pH of the sample. These extraction fluids are purposely designed to mimic the liquid that are produced in a municipal landfill from infiltration of surface water. It is imperative that the correct extraction fluid, based on the initial pH of the sample, be used. The use of incorrect extraction fluid will give erroneous results.
Values of analytes vary from lot to lot.
Analytes:
Arsenic
Barium
Cadmium
Chromium
Lead
Mercury
Selenium
