Zirconium fluoride, a raw material for halide glass manufacturing, was analyzed for the determination of traces of iron and copper by inductively coupled atomic emission spectrometry (ICP/AES), according to a previously developed method. Several techniques of removing these two impurities were studied. Solid liquid extraction, chelation and adsorption on resins, electrodeposition at a platinum cathode and at a mercury cathode were developed and tested. The removal of the two impurities (Fe 4.3 and Cu 20.2 mug/g) was in the range 80-96% for the techniques tested.

Abstract
Zirconium fluoride, a raw material for halide glass manufacturing, was analyzed for the determination of traces of iron and copper by inductively coupled atomic emission spectrometry (ICP/AES), according to a previously developed method. Several techniques of removing these two impurities were studied. Solid liquid extraction, chelation and adsorption on resins, electrodeposition at a platinum cathode and at a mercury cathode were developed and tested. The removal of the two impurities (Fe 4.3 and Cu 20.2 mug/g) was in the range 80-96% for the techniques tested.
