GB/T 14635.3-1993 Chemical analysis methods for rare earth metals and their compounds - EDTA titration method for determination of total rare earth content in heavy rare earth metals and their compounds

This standard specifies the determination method for the total content of rare earth elements in mixed rare earth metals with heavy rare earth holmium, erbium, thulium, ytterbium and lutetium as the main components and the total content of rare earth oxides in their compounds (oxides, hydroxides, fluorides and chlorides). This standard is applicable to the determination of the total content of rare earth elements in mixed rare earth metals with heavy rare earth holmium, erbium, thulium, ytterbium and lutetium as the main components and the total content of rare earth oxides in their compounds (oxides, hydroxides, fluorides and chlorides).
