X-ray photoelectric spectroscopy determination of a conceptual leaching model of retorted oil shale
Journal Article

Two hypotheses are proposed to describe the leaching of solid wastes. One hypothesis involves formation of a leached zone around particles of solid waste in contract with water, resulting in a diffusion barrier to release of soluble pollutants. The other hypotheses relies on pore diffusion and surface reaction as the dominating mechanisms controlling leachate release. X-ray photoelectric spectroscopy (XPS) is used to help determine which model more closely describes leaching of retorted oil shale. Although some evidence of possible Al(OH)/sub 3/ precipitation and relative depletion of sodium on the surface is found, a leached zone is apparently not formed on retorted oil shale during leaching. 34 references, 5 figures, 6 tables.
