Synthesis of Diatomite/WO-PAM Composite Adsorbent and Its Performance for Cesium Removal
Translated Abstract
In this work, two composite absorbents, including diatomite/WO-cation PAM and diatomite/WO-anion PAM were prepared via chemical synthesis method by using N, N-methylene bis acrylamide as crosslinking agent and azodiisobutyronitrile as evocating agent. The samples were characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), Brunauer-Emmett-Teller (BET), and Fourier transform infrared spectrometry (FT-IR). With CsCl as the source of133Cs, the adsorption behavior for133Cs of the two samples was investigated. It was found that the surface areas of the two samples were 88 and 92m2/g, respectively, and the maximum adsorption capacity for133Cs were 165 and 217mg/g, respectively. As initial concentration of133Cs was 10mg/L, the removal efifciency of both the diatomite/WO-cation PAM and diatomite/WO-anion PAM for133Cs was 99%.
