Outline of Final Research Achievements

In recent years, research on phosphorus circulation has started, which utilizes the difference of stable isotope ratio of oxygen in the phosphate. In order to measure the stable isotope ratio of oxygen in phosphate, it is necessary to separate and concentrate phosphate, convert it into silver phosphate (solid), and measure it with an isotope analysis mass. However, current methods cannot separate phosphate and phosphate compounds. This time, we were able to separate phosphate and phosphate compound using a commercially available Seppak cartridge.

Academic Significance and Societal Importance of the Research Achievements

今までの濃縮・分離方法では共存するリン酸化合物と必要なオルトリン酸との分離が不十分であった。今回開発した方法は共存するリン酸化合物の影響を受けずにオルトリン酸のみを濃縮・分離でき、また市販のカートリッジを利用する等それほど複雑な操作が必要な方法ではないため今後利用される可能性は高い。
