Determination of molybdenum content in molybdenum iron by 8-hydroxyquinoline weight method
On the basis of referring to GB/T 5059.1-2014,dissolve the sample in dilute nitric acid,use EDTA as a masking agent,precipitate molybdenum in the form of hydroxyquinoline salt in a pH 4.0 molybdenum buffer solution,filter,dry,and weigh the anhydrous hydroxyquinoline salt.This analysis method can quickly and accurately determine the molybdenum content in ferromolybdenum,and meet the large-scale production needs of daily enterprises.
