| 摘 要： | 选取农业副产物葵花籽壳作为吸附剂,研究其对溶液中铀酰离子的吸附性能。用元素分析、扫描电镜、红外光谱分析等方法对吸附铀前后的葵花籽壳进行分析和表征,通过静态实验分别研究了时间、温度、pH值、铀酰离子初始浓度、葵花籽壳用量等因素对吸附效果的影响。结果表明:吸附的适宜pH为5.0~6.0,35℃下,当铀溶液初始质量浓度为50mg/L,溶液pH=5.0,葵花籽壳质量浓度为1.00g/L时,饱和吸附量可达29.2mg/g。

| Abstract: | Adsorption characteristics of sunflower seed shells have been studied for U(Ⅵ) removal from aqueous solution. The sunflower seed shells were characterized by elemental analysis, scanning electron microscopy, and FT-IR. Adsorption of U(Ⅵ) from aqueous solution by means of sunflower seed shells was studied in a series of batch experiments. The adsorption behavior of U(Ⅵ) onto the adsorbent was investigated as function of pH value, contact time, initial U(Ⅵ) concentration, temperature etc. The results show that the adsorption capacity is 29.2 mg/g at the pH=5.0 and 35 ℃ with initial U(Ⅵ) mass concentration 50 mg/L and adsorbent dose 1.00 g/L. |
