Process for treating metal-contaminated materials

Image Number 9 for United States Patent #5245120.

A process for treating wastes contaminated by toxic metals and/or organic materials is disclosed. The process involves heating the metal-contaminated wastes to a temperature sufficient to volatilize the metals. This temperature is also high enough to destroy or volatilize organic contaminants. The metal vapors are contacted with a sorbent which is reactive with the metals and sequesters them, thereby forming a non-leachable complex which can be disposed as non-hazardous conventional waste.
