Description

Deuterium concentration in heavy water was determined gas chromatographically. Heavy water was decomposed by using LiAlH4. Heavy water reacted with LiAlH4 in short time and both H2 and HD were generated. D2 was not formed in this reaction. When hydrogen was used as a carrier gas, only a peak corresponding to HD was observed and therefore deuterium concentration in heavy water was determined as HD.<BR>The plot of HD peak height against deuterium concentration in heavy water was found to be linear in the range of deuterium concentration from 0 to 42 atom%. The relative error was below 6.9%. This method can be applied to a small amount of water sample. It is relatively simple, and can work as a conventional method of analysis.
