Cation Exchange Behavior of Molybdenum () and Tungsten ()

[摘要] The separation and species of MoO42- and WO42- at the various PH value have been studied by the method of cation exchange chromatography. Elution curves of MoO42- and WO42- have been made with a 5 cm column of the resin, Dowe ¡¿ 50 W ¡¿ 12(100-200 mesh), using solutions of various PH value as eluent. Complete separation of MoO42- and WO42- was obtained in each PH of 10% EtOH. According to the evaluation of peak position and number of peaks of elution curves, it is likely to exist cationic species of MoO42-.
