Abstract : A procedure is reported for the determination of trace amounts of molybdenum and niobium in tungsten using a comparatively small column. Tungsten, the matrix material, passes through the column while the impurities, molybdenum and niobium are adsorbed by the anion ex change resin. Molybdenum and niobium are then selectively eluted from the resin column and determined spectrophotometrically. (Author)
