摘要:
Bismuth can be determined with various chromogenic agents, such as xylenol orange and Bromopyrogallol red-Ethyl violet. In most of the methods, the sensitivity is very poor. The spectrophotometric determination of tellurium(IV) as ion-association complex of the tellurium with tungstate and nile blue in aqueous solution in the presence of polyvinyl alcohol(PVA) has been reported.
