Analysis of deuterated water contents using FTIR bending motion
- 56 Downloads
Novel method for detection of heavy water in mixture has been developed based on bending vibration instead of stretching vibration. In order to apply bending motion, equation derived from equilibrium kinetics is established to find amount of HDO at equilibrium to define internal standard of analytical tool (in the concentration range of 20–80%). Based on theoretical expectation about amount of HDO and FTIR bending spectra, one can measure the initial concentration of heavy water in certain concentration range. The analytical method presented here can provide additional experimental pathway to determine exact amount of heavy water with better accuracy.
