Item Metadata only Qualitative and quantitative analysis of multivalent vanadium ions in sulphuric acid electrolyte(Mahidol University. Mahidol University Library and Knowledge Center, 1998) Pattama Nopparat; Waret Veerasai; Juwadee Shiowatana; Duangjai NacaprichaAnalytical methodologies for characterization and determination of vanadium in vanadium electrolyte solutions in sulphuric acid media have been developed. Determination of total vanadium over a wide concentration range was performed using atomic... absorption spectrometric technique for the ppm region, and by UV-VIS spectrophotometric and potentiometric techniques for the higher concentration region. Standard addition was required for determination of total vanadium and trace impurities, such as Cu, Fe
