Abstract :
The removal of heavy metals from industrial environments is one of the most important environmental issues, and so far many methods have been considered to remove or reduce these metals, which is the use of high voltage ionization to produce negative ions, due to its economic nature, easy access. And in accordance with environmental standards, high efficiency to reduce the frequency of their presence in the environment. When a potential difference is applied between the conductors, a potential gradient is formed in the air, the maximum value of which is at the conductor surfaces. Under the effects of the potential gradient, the available free electrons gain a higher speed. As the applied voltage increases, the potential gradient increases and the speed of free electrons increases. When the potential gradient of the surface of the conductor reaches about 25-30 kV/cm (maximum value), the speed of free electrons will be sufficient to collide with neutral molecules, and the force will be sufficient to separate one or more electrons from it.
