  • Catalytic Determination of Molybdenum by Means of the Sodium Perborate Bromide Ascorbic-Acid Landolt Reaction Using Potentiometric Measurements
  • Published at:Not Found
  • A new catalytic method for the determination of 0.1-10 ppm molybdenum is described. Molybdenum catalyses the perborate - bromide ascorbic acid Landolt reaction at pH 3.64. The rate is monitored by potentiometry. A calibration graph is based on the ratio of the reaction times for the blank and the sample, (t(o)/t(c), plotted against the concentration of molybdenum. Optimal conditions for the determination are discussed. Also the effect of various ions and interferences, are described.
