| Abstract: | Purpose Most previous studies focused on the metal extraction efficiency of chelant-enhanced soil washing under various operational
conditions; however, one of the keys to cost-effective field application is to maintain a high throughput rate (i.e., short
washing time) while achieving the treatment objectives. Therefore, this study presented a conceptual model for simulating
the kinetic extraction of heavy metals and evaluated its sensitivity analysis to the predetermined parameter values in five
soils with different initial metal distributions. |
