Chemical Extraction CPEO

Chemical Extraction . Chemical extraction is a process that separates contaminants from soils and thereby reduces the volume of the hazardous waste that must be treated. The process differs from soil washing, which generally uses water, and varies with contaminant and soil type. Often, physical separation is used before chemical extraction on the assumption that smaller particles contain most
