This paper reports the anodio stripping voltammetry of trace amount of tellurium on a gold film which is deposited on a glassy graphite electrode.In 0.1M perohlorio acid medium,a peak of stripping current of tellurium appears at +0.55~+0.65 V(va.N Ag/AgCl).It shows a linear relation between the peak area and the conoentrsficu of tellurium in the range of 1.010-9M to 5.0×10-6M.This method is one of the moat sensitive methods for the determination of tellurium.Furthermore,we have studied the electrode process with the triangle cyclic valtrammetry.It shows that the electrod.reaction is irreversible and it is possible that the deposition of tellurium on the gold film electrode results in the formation of an intermetallio compound between tellurium and gold.Arsenic seems to behave similarly.
