摘要
The sorption of uranium(VI) from aqueous solutions was investigated using synthesized amidoximed silica. Batch experiments were conducted to study the effects of contact time, initial solution pH, solid-liquid ratio, initial uranium concentration and coexisting ions on uranium sorption. The desorbing of uranium was also investigated. The maximum uranium sorption capacity onto amidoximed silicate was estimated to be 156 mg g(-1) under the determined optimal experimental conditions. This work suggested that amidoximed silicate can be used as a highly efficient adsorbent for uranium removal from aqueous solutions.
