Scope

This Part of GB/T 16484 specifies the method for determining the amount of
ammonium chloride in rare earth chlorides and light rare earth carbonates.
This Part is applicable to the determination of ammonium chloride content in rare earth
chloride and light rare earth carbonate. There are two methods in total. Method 1 is
distillation-titration method. Method 2 is distillation-colorimetry method. In Method 1,
the determination range (mass fraction) of rare earth chloride is 0.30% ~5.00%, and the
determination range of light rare earth carbonate is 0.30% ~30.00%. In Method 2, the
determination range (mass fraction) of rare earth chloride and light rare earth carbonate
is: 0.005 0% ~1.50%.
