Leachability of Waste Glass Systems - Physical and Mathematical Models

The primary objective of this report is to analyze a growing body of leachability data to determine if existing concepts and models describing leachabilities of simple glasses apply to the more complex waste glass systems. Since the leachability behavior of waste glass forms failed to conform to existing models, a new model was developed based on diffusion of soluble components through the developing surface layers. While this model, called the SRL Leachability Model, does not yet completely describe all aspects of the leachability of SRP waste glasses quantitatively, it does represent the data more accurately than other existing models. This model will be improved as more data become available.
