摘要：
Effects of various concentration uranium solutions on uranium accumulation and growth parameters of Cyperus iria L. were studied. After exposed to uranium solutions for 30 d, the U concentrations (dry weight) in its roots ranged between 4,158 ±611 mg/kg for 100 mg/L uranium solution and 48,605 ±1266 mg/kg for 2,500 mg/L uranium solution, the U concentrations in its shoots ranged between 366 ±26 mg/kg for 100 mg/L uranium solution and 8,224 ±856 mg/kg for 2,500 mg/L solution concentration, respectively, and these were only 1/5-1/10 of those in the roots. All the growth parameters except grade of growth inhibition had the similar tendency. They would come to a peak at a U concentration between 100 mg/L and 250 mg/L and then steadily decline with a sharp decrease between 500 and 2,500 mg/L U.

摘要：
This study focuses on developing a new method to remove uranium from aqueous solution. Chitosan and ferrous ions were used together to remove uranium ions from aqueous solution. Through two-step pH adjustment, the uptake behavior of chitosan and ferrous ions toward uranium in aqueous solution using batch systems was studied in different experimental conditions. The experimental results indicated that the removal of uranium by the synergetic effect of chitosan and ferrous ions was more effective than the way of adsorbing uranium ions by chitosan alone. Under the given experimental conditions, the concentration of the residual uranium in the effluent after the chitosan and ferrous ion treatment could meet the discharge standard (< 0.05 mg l(-1)) when the initial concentration of uranium ions was 10 mg l(-1) or 100 mg l(-1). The synergetic effect of chitosan and ferrous ions, including adsorption, coacervation, and coprecipitation, was responsible for the high removal rate of uranium. [DOI: 10.1115/1.4002817]
