摘要：

Adsorption experiments were carried out to investigate the removal of Cs-134 radionuclide and methylene blue (MB) from aqueous solution using poly(acrylamide-itaconic acid)/N,N'-methelyenediacrylamide/zirconium hydrous oxide composite [poly(AM-IA)/DAM/Zr(OH)(4)] as an adsorbent. The effects of initial pH value, initial concentration of Cs or MB, adsorbent dose, contact time and temperature on adsorption were investigated. Characterization of the prepared composite was carried out using FT-IR, XRD, TGA, DTA, and SEM. The adsorption behaviors showed that the adsorption kinetics and isotherms were in good agreement with the pseudo-second-order and the Langmuir models indicating the chemosorption mechanism. Thermodynamic studies were carried out and it was found that the process was spontaneous exothermic in nature. Discussion of the results of the adsorption behavior showed that the prepared composite can be used as a promising adsorbent for removal of Cs-134 or MB.
