The electroreduction behavior of antiarrhythmic drug propafenone at Hg electrode was studied by means of linear sweep polarography,and a new determination method of propafenone in factual samples was developed. In solution with pH<11.6,only one reduction peak was observed in the linear sweep polarogram and the mechanism of the peak was studied.
In present paper the properties of the pseudo polarograms of Arsenic at a gold electrode are stud - ied.
