Comparison analysis of wet digestion and stripping methods on recovery of lithium isotopes in the loaded phase

6 Li and 7 Li play important roles in the nuclear industry. In this study, the recovery of lithium isotopes in the loaded phase after extraction was compared for the first time between the stripping and wet digestion method. The results showed non-significant differences in the data obtained after processing in the two methods. The recovery of lithium isotopes by wet digestion is simple and complete. But it destroys the organic phase and requires heating at high temperatures, making it suitable for handling small amounts of samples. The stripping method is recommended for sample processing because it involves lesser chemical reagents and related hazards without damaging the sample.
