説明
Abstract Molybdenum(VI) ions are adsorbed on Sephadex G-25 gel at pH 3.5. and are desorbed reversibly with a complexing agent, EDTA. The adsorbability is much greater than that for boron(III) and vanadium(V). Large amounts of sodium chloride have little effect on the adsorption. Molybdenum concentrations in natural waters, especially in seawater, can be determined with good precision and accuracy after selective preconcentration of molybdenum by a Sephadex G-25 gel column. The detection limit for 250-ml water samples is about 1 μg l -1 by atomic absorption spectrometry or by spectrophotometry with bromopyrogallol red as reagent.
