Nature of glass leaching

PDF Version Also Available for Download.

Description

Several models have been proposed in the literature to describe glass leaching behavior in aqueous solutions, but they are primarily applicable to relatively simple glasses. Their shortcoming is that they do not incorporate enough of the phenomena occurring during leaching. Leaching characteristics of a complex waste containment glass are discussed. Gamma irradiation increases the leach rates. Since bulk diffusion does not play a major role in leaching, the existing models are totally indequate for complex glasses. 4 figures, 3 tables. (DLC)
