The concentration of noble metals such as Pd, Pt and Au in seawater and river is very low (<1 pmol/kg). Since these metals form inert complexes, chemical separation of them is difficult. A few distributions of the noble metals in the ocean have reported.From the above, clean technology development in order to obtain the exact distribution of the noble metal element is essential In this study, we are developing a new method to determine the distribution of the noble metals accurately. We used chelating resin-solid phase extraction and measured the concentration of the noble metals by high-resolution (HR)-ICP-MS.

The determination of iodine-129 in environmental samples is very difficult by ICP-MS due to its relatively low sensitivity, high background caused by ¹²⁹Xe impurities in the argon plasma gas and possible polyatomic interference from ¹²⁷IH₂⁺. The relatively poor abundance sensitivity of conventional ICP-MS is a problem of particular importance for ultra low-level analysis of any elements such as radionuclide elements which are adjacent in mass to elements of much higher natural abundance.In this study, in order to overcome the challenges due to the relatively poor abundance sensitivity of conventional ICP-single quadrupole MS, a newly developed triple quadrupole ICP-MS (ICP-QQQ) technique using oxygen as the reaction cell gases was applied to determine ultratrace levels of those radionuclides in aqueous samples. We improved the measurable ratio of ¹²⁹I/¹²⁷I and lower the detection limit for ¹²⁹I without loss of abundance sensitivity.

Halogen is expected to be a good tracer of water in the mantle. In order to determine the trace amount of halogen in the mantle-derived rocks, noble gas method can be an useful method. In this method, samples are irradiated with neutron in a nuclear reactor and then some elements generate corresponding noble gas isotopes. They are simultaneously determined by noble gas analysis.We had developed noble gas analysis system which can be applied to halogen analysis. For more precise analysis and detection of smaller amount of halogen, we developed new analysis system and evaluate it.

We have been developing analytical tools for investigation of the hydrothermal origin of life. Conclusively, we succeeded to establish a flow reactor system, which enables monitoring reactions at 400 ^oC at 30 MPa within 0.002 - 200 sec. In addition, we developed an in situ monitoring system of UV-Vis-NIR absorption spectra. However, these tools are not applicable for realistic dynamic hydrothermal reactions in the presence of minerals. Thus, we attempted to develop a mineral-mediated hydrothermal flow reactor system and finally we succeeded to construct a monitoring system at 300 ^oC within 2 - 200 sec with naturally occurring mineral particles. By using the new reaction tool, we found that the peptide elongation reaction, which was discovered at 2005, is enhanced in the presence of carbonate minerals; the elongation yield reached to ca. 30 %. This new research tool is applicable for reaction analysis and kinetics of different types of hydrothermal reactions in the presence of mineral particles.

in our study, Ca and REE compositions of seven kimuraite samples were measured with ICP-MS and EMPA. From the backscattered electron images, that another mineral was precipitated in the cleaveges of kimuraite was first documented, and this mineral was most likely to be lanthanite.meanwhile, we conducted another study applying the REE data reported by now to the theoretical equation of tetrad effect. when comparing the chondrite-normalized REE patterns to the theoretical tetrad patterns calculated by the equation, two types of kimuraite were recognized.

To reveal temporal relationship between Kurihashi and Ganidake granitic bodies in the Kitakami Mountains, we performed K-Ar dating for biotite and hornblende concentrates from six granitic rocks. K-Ar ages range from 130-110 Ma with one exception. There are no obvious differences between the K-Ar age of Kurihashi and that of Ganidake bodies. Also, no apparent age difference between the biotite and hornblende concentrates. Detailed petrological and mineralogical investigations are necessary for interpreting this K-Ar dating results.
