| Outline of Final Research Achievements |
To understand the behavior of the combustion and drying of organic samples for tritium analysis, we conducted TG/DTA analysis of pine needle samples. Next, we tried the water recovery from fresh pine needle samples by the multi-mode microwave heating system. It was provided to good recovery yield achieved more than 97% under these experimental conditions.
We made a new microwave heating furnace based on the results of preliminary test. As the results, we were able to recover the FWT samples in a few hours. And we were able to be combusted organic matter in approximately 1 hour. And we were able to recover the OBT sample. FWT and OBT sample water contain no organic matter. Therefore, we can analyze directly without distillation. These result shows more preferable for the pretreatment of organic samples by microwave irradiation method than the conventional method.
