Abstract:
Polyacrylic acid, Chitosan and nanosilica particles composite (PCNS) was prepared for enrichment of U (VI) from aqueous solutions. Adsorption tests controlled by different parameters including contact time, pH, initial concentration of UO2 (2+) and coexistence ions were examined. FTIR, SEM and EDX studies proved the formation of composite and confirmed efficient adsorption of UO2 (2+) by PCNS. The experimental datas fit the Langmuir and pseudo-second-order models, the R (L) (0.115-0.645) indicates the adsorption of UO2 (2+) onto PCNS are favorable. The value of q (m) (451.118 mg g(-1)) and adsorption-desorption experiments showed PCNS hydrogel can be reckoned as a high efficienct and sustainable material for removal of U (VI).
