| Abstract: | In this paper the film - forndng mechanism of CuSe on copper electrode in 1. 0mol· L-1 H3PO4 c0ntaining H2SeO3 was studied by using in situ electrochendcal ultraviolet-visiblerenectance spetroscopy. The results combined with thermedpoamic analysis confirmed the exis-tence of direct-okidizing mechanism. |
