Use of a new leaching test framework for evaluating alternative treatment processes for mercury-contaminated soils

摘要

A new framework for evaluating leaching of wasters was used for assessing the efficacy of potential treat- ment processes for mixed wastes (radioactive and hazardous) that contain mercury. This framework is based on measurement of intrinsic leaching properties of the material of concern and using the testing re- sults in conjunction with assumed management scenarios and mass transfer models to estimate release of constituents of potential concern over a defined time period. Two mercury-contaminated soils (ca. 4500 mg/kg) were used for the demonstrations.
