摘要：

Spectrophotometric determination of rhodium(Ⅲ) has been studied in the presence of polyvinyl alcohol(PVA). Rhodium(Ⅲ) reacts with sodium tungstate to form a tungstorhodic acid complex. The ion-association complex of tungstorhodic heteropoly species with butylrhodamine B(BRB) is formed in the presence of polyvinyl alcohol.
