Abstract
BS>A method for the determination of zirconium in the eresence of lange quantities of molybdenum and tungsten, without their separation beforehand, is based on zirconium precipitation with cupferron at pH 6.8 in the presence of tartaric and oxalic acids to retain molybdenum and tungsten in solution. The method permits the rapid and precise determination of zirconium in molybdenum and in tungstenbase alloys. (auth)
