Simulation of migration colloidal gold in surface waters of natural

With the purpose of studying migration and accumulation nature of the colloidal metal forms in natural and anthropogenic environments the conditions for nanoscale metal forms, stabilized by low molecular and macromolecule organic ligands with the example of gold were defined. The kinetics and completeness of obtained particle concentrating with goethite (FeOOH) in circum neutral environments were studied. It is established, that gold particles stabilized with natural ligands of humus nature, interact with goethite most quickly, providing both efficient colloid transport of gold and its deposition on geochemical barriers.
