01950 IUPAC Gold Book - electrodecantation 10.1351/goldbook.E01950 E01950 current synonym: electrophoresis convection 1 Electrodialysis may lead to local differences in concentration and density. Under the influence of gravity these density differences lead to large scale separation of sols of high and of low (often vanishingly low) concentrations. This process is called electrodecantation.
