【 摘 要 】

The presence of certain metals defined as hazardous by the Resource Conservation and Recovery Act (RCRA) in mixed-waste drums can seriously limit the operation of waste treatment processes, especially at waste incinerators. Excessive concentrations of mercury, cadmium and lead in the process feed may either result in offgas emission concentrations which exceed regulatory limits and/or interfere with the treatment process control. There is currently no adequate nondestructive assay (NDA) technique to monitor the RCRA metal content of mixed-waste drums.
