An electrochemical method for the in situ purification of heavy metal fluoride melts has been developed. Several factors which influence the efficiency of purification such as electrode materials, rotation rate, temperature, deposition time and purification times have been studied. The purified glasses were analyzed using graphite furnace atomic absorption spectroscopy (GFAAS). The results show that Fe, Cu and Ni impurities in fluoride glass melts can be reduced to the level of 0.3–0.5 ppm.
