研究了改性甘蔗渣对铀的吸附性能,试验确定了改性甘蔗渣吸附铀废水的最优条件:当铀浓度20 mg/L、pH=4.0、温度25℃、吸附剂用量为20 g/L,吸附时间为90 min,吸附效果最佳.用红外光谱研究了吸附剂改性前后及吸附铀后结构变化.

The adsorption properties of modified bagasse for U（Ⅵ） were studied.It showed that the adsorption efficiency increased obviously,when U（ Ⅵ） concentration was 20 mg / L,temperature was 25 ℃,adsorbent dosage was 20 g / L at pH 4. 0 and reached equilibrium in 90 minutes.The adsorbent was characterized by Fourier transform i...
