GB/T 16484.13-2017 Chemical analysis methods for rare earth chloride and light rare earth carbonate—Part 13:Determination of ammonium chloride content
Abstract
This part of GB/T 16484 specifies the method for determining the amount of ammonium chloride in chloride rare earths and light rare earth carbonates. This part is applicable to the determination of the amount of ammonium chloride in chloride rare earths and light rare earth carbonates. It includes two methods: Method 1, distillation titration; Method 2, distillation colorimetry. In Method 1, the determination range of chloride rare earths (mass fraction) is 0.30%~5.00%, and the determination range of light rare earth carbonates is 0.30%~30.00%; in Method 2, the determination range of chloride rare earths and light rare earth carbonates (mass fraction) is both 0.005%~1.50%.
