The effect of the LASER-induced desorbtion in inversion voltammetrie

The operating of a low-power laser radiation on electrochemical processes of dissolution of lead was studied in solutions of 0,1 MKCl with pH from 0,95 to 3,35 at the presence of butanol. Under operating of butanol an altitude of the peak of electrodissolution of lead decreases, then, at effect of a laser radiation on a electrode peak step-by-step grows. The altitude of the obtained peak makes up to 80% from an altitude of an original signal. Used low-power laser radiation does not cause heating of a surface, and it is supposed, that the desorption of molecules of butanol takes place owing to elastic interplay of a laser radiation to coherent radiation.
