Room-temperature adsorption behavior of cesium onto calcium silicate insulation

A calcium silicate insulator material was investigated for its interaction with non-radioactive cesium at room temperature by batch-type adsorption experiments. An industrial-grade calcium silicate was weighted and ground into powder with an average size of 15.4 ± 0.1 μm, which was then placed into...
