铀矿开采,铀应用过程中产生大量的含铀废水,造成土壤和地下水中的放射性污染,对环境和人体健康造成危害,因此对含铀废水的治理成为研究热点.本研究以向日葵叶提取液做还原剂和稳定剂,绿色合成膨润土负载零价纳米铁(SF-NZVI/BT),用于去除废水中铀酰离子.并探讨pH、投加量、时间、温度、阴阳离子干扰等因素对去除效果的影响.结果表明,含铀废水的初始pH对SF-NZVI/BT去除铀的效果影响显著,在弱酸性条件下有较好的去除效果;在30℃温度下、PH=6、投加量为0.075g、U(Ⅵ)的初始浓度为10mg·L-1、接触反应90min时去除效率达到98.87％;Ca2+、Cu2+、Mn2+、F-、CO32-、HCO3-、SiO42-等阴阳离子对铀的去除具有...

There will produce large amounts of uranium-containing wastewater in uranium mining and uranium production process.and dangerous to human health and environmental protection,the removal of uranium from the wastewater is a promising filed of research in recent years.Sunflower leaf extract were used as reducing and capping agent to synthesize Nanoscale Zero valent Iron supported on Bentonited by green synthesis methods.and removal of uranium from the wastewater by the SF-NZVI/BT.The effects of the experimental conditions,such as pH,the dosage of ...
