摘要
本论文用可见光分光光度法研究了新型吸附剂石墨烯对水中铀的吸附行为,考察了溶液pH值、吸附时间,吸附剂浓度对吸附率的影响。结果表明,pH值、时间吸附剂浓度变化均对于吸附率有影响,pH为7.61时吸附率达到最高值;吸附剂浓度到达160 ppm时吸附率达到最高值;吸附时间到达250 min时,吸附速率开始减慢。
In this paper, a new type of adsorbent are studied by visible spectrophotometry graphene adsorption behavior of uranium in water, the solution pH value, adsorption time, the influence of the concentration of adsorbent adsorption. The results showed that the ratio of pH and time adsorption was affected by the adsorption ratio, and the adsorption ratio reached the peak at 7.61. The adsorption ratio reached the maximum when the adsorbent concentration reached 160ppm. When the adsorption time reached 250 min, the adsorption rate began to slow down.
