Recovery of Heavy Metals from a Polyethoxylated Alcohol

Abstract

Metals often appears in very high concentrations in many solid, and liquid industrial discharges.
The storage of such waste in controlled landfill site does not justify the absence of any risk of contamination.
Lead and copper are a heavy metals that have been widely used in metallurgy since ancient times and was
rediscovered during the industrial revolution.
The could point process is a technic that uses non-ionic surfactants as metal extractant based on there could
point temperature. In recent years, ionic liquid known as a green solvent, wish also have surfactants
properties, have become interesting tool in hydrometallurgical process for separating metal ions, where
they are beginning to replace many expensive, toxic and non-biodegradable organic solvents.
This technic has made it possible to recover 82 % of lead and 74% of copper.
