Iontophresis is a phenomenon in which charged particles and ions move through a liquid or gas, resulting in the creation of an electric field. This process occurs as a result of an electrical voltage that is applied to electrodes located in a liquid or gas. As a result of the ionic current, ionically mobile ions are transferred from the liquid to the electrode surface, where they are absorbed and can be removed. This phenomenon has wide applications in various fields such as chemistry, medicine and engineering. In particular, iontophoretic separation can effectively separate solids from a liquid or mixture of liquids, as well as remove residual impurities from chemical processes. Additionally, ionic conduction can be used to create highly efficient batteries and other devices that use electricity. In ion sieving, electrical charges are created on particles that are present in a solution, which can be used to control the flow of liquid that passes through the electrode. This can lead to various effects, for example, an increase in the speed of movement or concentration of particles, as well as changes in their properties. Ionic analysis is a method that is widely used in scientific research, pharmaceuticals, food processing and other fields.
