Behavior of phenol and aniline on selected sorbents and energy-related solid wastes

Phenols and aromatic amines constituted a significant fraction of the water-soluble organic compounds present in the liquid wastes from the combustion and conversion of fossil fuels. The sorption and desorption of this fraction on selected soils and soil components and on solid waste materials generated in fossil fuel utilization and conversion were investigated, with particular reference to phenol and aniline. Isotherms determined from sorption experiments were generally nonlinear and conformed to the Freundlich equation. The sorption of phenol and aniline could not be defined by a single sorbent characteristic, but was affected by both the organic and the mineral components present.
