Abstract Molybdenum was determined by its catalytic effect on the reduction of nile red with
hydrazine dihydrochloride. The method was based on measuring the decrease in
absorbance of nile red after 3 minutes at 595 nm at 30° C. The calibration curve was linear
over the range of 50–30000 ng. ml− 1. The detection limit was 30 ng. ml-1 of Mo (VI). A
cation exchanger resin was used to remove interfering ions. Plant materials and steel were
used for the determination of molybdenum content. The relative standard deviation was ...
