The Role of Ionization in the Formation and Evolution of Submicron Aerosol Particles

Abstract

Experimental studies estimating the effect of ions produced by corona discharge on the formation of new aerosol particles are analyzed. It is noted that, not only in a controlled space (aerosol chambers), independent of its volume, but also under conditions of the natural atmosphere, the generation of a corona discharge is accompanied by the formation of new nanometer-sized aerosol particles, the concentration of which exceeds the background concentration by more than an order of magnitude. The results obtained are interpreted on the basis of theoretical views about the effect the electric charge of ions has on the condensation of different admixtures. The coagulation theory and the model of a continuous growth were used to calculate the increase in the radius of aerosol particles as a function of time.
