Determination of inorganic anions and cations in some vegetable juices was examined by ultraviolet photometric ion chromatography with a conventional HPLC system equipped with a UV monitor and a separating column packed with popular ion exchangers. Inorganic anions such as Cl^-, NO_3^-, and SO_4^<2-> in sample solution were completely separated on a Zipax SAX packed column (50 cm × 2.1 mm I. D.) with 5 × 10^<-3> M disodium phthalate as an eluent and detected at 240 nm. Inorganic cations such as Na^+, NH_4^+, K^+, Mg^<2+>, and Ca^<3+> in sample solution were completely separated on a Zipax SCX packed column (25 cm × 4.6 mm I. D.) with 2.5 × 10^<-3> M copper sulfate as an eluent and detected at 220 nm. Under the conditions described above, the three anions in juices of Chinese cabbage, tomato, and radish, and the five cations in Sep-pak C_<18> treated juice of Chinese cabbage were determined.
