Iodine and tin are important elements in performance assessment of geological disposal of radioactive wastes. Sorption experiments of iodine were carried out under varying nitrate concentration with a range of 0 to 5 mol dm at neutral pH range in order to determine the distribution coefficient of iodine was zero or non-zero value. The experimental results with estimated statistical errors showed non-zero values for tuffaceous sandstone except for NaNO concentration 0.5 mol dm. Non-zero values were also obtained under NaNO concentrations higher than 0.5 mol dm for granodiorite. Sorption experiments of tin were carried out at high pH range in order to check whether the distribution coefficient of tin decreases significantly with pH as a result of formation of anionic hydrolysis species of tin. The distribution coefficients of tin on granodiorite decreased from 9.7910 m kg at pH10.4 to 2.4610 m kg at pH12.4. The distribution coefficient of tin on tuffaceous sandstone was about one order of magnitude higher (about 210 m kg) than that of granodiorite at pH around 12.4.

Times Cited Count:22 Percentile:58.10(Chemistry, Physical)The location of the liquidus in the low-pressure crystalline phase of SnI was determined utilizing X-ray diffraction measurements under pressures up to approximately GPa. The liquidus is not well fitted to a monotonically increasing curve such as Simon's equation, but breaks near GPa and then becomes almost flat. The results are compared to those from molecular dynamics simulations. Ways to improve the model potential adopted in the simulations are discussed.

Distribution coefficient of Sn onto Na-type and Ca-type montmorillonite samples was determined under high-pH conditions with a batch method. It was suggested that sorption behavior of Sn under cementitious conditions was affected through changing major aqueous species accompanied with pH change.

Hydrogen embrittlement (HE) is an inevitable problem in strengthening aluminum alloys. In the alloys, H diffusively segregates into interfacial defects such as grain boundaries and phase interfaces, weakening the atomic bonds there and causing embrittlement. Hence there is a possibility to suppress HE by reducing the interfacial segregation of H. Recently, atomic-level calculations have revealed that a second-phase particle of tin (Sn) in aluminum alloys can trap H in its interior. Furthermore, suppression of HE has been reported experimentally in tin-doped aluminum alloys. In this study, a code for simulating H diffusion in duplex steels was applied to H diffusion in aluminum containing a Sn second-phase particle to evaluate the possibility of H penetration into the particle according to the experimental conditions. As a result, it was confirmed that some amount of H can penetrate into the particles. This contributes to the verification of the experiment by simulation.
