A Zn or Fe particle bed to convert HF with traces of TF to HT

The generation of HF with traces of TF and then conversion to HT were investigated using a bed packed with NiF₂ and Zn or Fe particles. When the temperature of fine particles of Zn or Fe was elevated up to 400 °C or 550 °C, respectively, TF was completely reduced to HT. Since ZnF₂ and FeF₂ had no TF (and HF) adsorption capacity, memory effect was found to be negligibly small. Thus Zn and Fe particles can be used as an effective reduction material corresponding to different temperature conditions to convert TF to HT for tritium detection by ion chambers without any corrosion.This revised version was published online in November 2005 with corrections to the Cover Date.
