The glassy carbon electrode has been used as working electrode,
to study the electrochemical behavior of Se(IV), by using anodic
stripping voltammetric method (ASV) in acidic media HCl. We
found that The reason for the absence of analytical signal
s
expressed on flow any electrodic process due to reduction
mechanism of Se(IV) on glassy carbon electrode from Se4+to Se2-
and formation H2Se.
