What polarities are used in phoresis and anaphoresis?

Phoresis and anaphoresis are processes that involve the application of electrical current to facilitate the movement of ions in a solution. When using phoresis, which generally refers to the movement of particles through a medium due to an electric field, both polarities—positive and negative—are essential. They enable the directed movement of ions, where positively charged ions move towards the negative electrode (cathode) and negatively charged ions move towards the positive electrode (anode). This characteristic is crucial in treatments that utilize iontophoresis, where medications or other solutions are delivered transdermally, leveraging the movement of charged particles.

The use of polarities in these processes highlights their fundamental role in ensuring effective ion transfer and therapeutic outcomes. Understanding this principle is vital for the practical application of electrotherapy techniques within electrology.
