Process and apparatus for the removal of aromatic amines from soil and water

摘要

A process and apparatus for the removal of aromatic amines from soil and water is described. In particular, treatment trains are described in which soil washing or low temperature desorption process effect removal of contaminant, such as xylidines from soil and steam stripping is utilized to remove contaminant from water. Further treatment through organic acid precipitation and advanced oxidation produce clean water and precipitated salts which may be recovered.
