| Outline of Final Research Achievements |
The cesium ion absorption through bark and ion exchange on bark surface have been reported in the previous study. In this study, we aimed to understand the relationship between ion absorption and ion exchange in the barks of Cryptomeria japonica (Sugi) and Quercus serrata (Konara). The experiments were conducted using a double container, in which smaller one has a window covered with a bark. Salt solution and distilled water were filled in two containers separately and contacted with a bark window. The change in pH and ion concentration in the distilled water were observed. As results, we found the following phenomena; ①Na, K, and Ca were transported through bark, ②Ca was adsorbed the cell wall through the transportation, ③K was leached from the barks of both species, ④ion exchange between proton and cation occurred in the outer bark, and ⑤ there was a counter ion at cation transportation such as Cl.
