[2C11] Migration behavior of molybdate ion in bentonite

*Yuya Nakasaki1, Kazuya Idemitsu1, Yaohiro Inagaki1, Tatsumi Arima1 (1. Kyushu Univ.)

Keywords:bentonite, molybdate ion, filtering

In this experiment, we focused on the migration behavior of molybdate in bentonite and conducted a diffusion test using the diffusion period as a parameter. The test results showed that the concentration of molybdenum decreased exponentially with diffusion distance, which is thought to be a filtering phenomenon of molybdate ion.
