Removal of nickel and lead from natural clay soil through the introduction of EDTA and coupling ion exchange processes with electrokinetic methodology
In clay soils having low initial pH values, electrokinetic transport of heavy metals has proven to be effective. The transport of these metals is predicated on maintaining a low pH throughout the cell, which in turn keeps the metals in the pore water phase, where they are accessible to EK transport....
