Description

Silica based ammonium molybdophosphate (AMP/SiO2) adsorbent was used to remove Cs(I) from HNO3 solution. The adsorbent with different absorbed dose (0-300 kGy) was characteristed by X-ray power diffraction. The adsorption data against different γ-ray absorbed doses were analyzed by the Langmuir isotherm. The adsorption capacity decreased slightly from 23.22 to 22.37 mg/g with the increase of the absorbed dose. The breakthrough properties of Cs(I) were conducted using column packed with AMP/SiO2 before and after irradiation. The chemical stability of AMP/SiO2 at 300 kGy absorbed dose in 3 mol/L (M) HNO3 was excellent. (author)
