This paper reports the anodio stripping voltammetry of traoe amount of arsenio on the gold film whioh is depositeal on a glassy graphite eleotrode.In 1 M sulfuric acid medium,it shows a peak of stripping ourrent of arsenic at +0.15V+0.25 V(vs.1N.Ag-AgCl).A linear relation between the peak height and the ooncentration of arsenic in the range of 1.0×10^-9M to 6.0×10^-6M was observed,the sensitivity of this method is about 200 times:Eligher than that of the oolorimetry of arsenic with silver diothyldithio-carbamate.On the other hand,we havo studied the eleotrode process with the triangle cyolic voltammetry.It shows that the electrode reaction is irreversible and tho deposition of arsanio on the gold film electrode is probably due to the formation of intarmetallic compound of arsenic with gold.
