Lead Immobilization and Hydroxamate Ligand Promoted Chloropyromorphite Dissolution

Figure 4

(a) A comparison of equilibrium aHA or DFO-D₁ promoted dissolution of CPY as a function of pH compared to equilibrium CPY dissolution in the absence of ligands along with Visual Minteqa 2.6.1 model calculations; (b) model calculations of 0.01 M DFO-B versus 0.00024 M DFO-B promoted CPY dissolution.
