摘要
研究了以伯胺N_(1925)为流动载体,上胺N_(205)为表面活性剂,煤油为膜溶剂,Na_2CO_3试剂作内相解脱剂的乳状液膜法模拟处理含钒废水。确定了最佳条件。结果表明,对500 mg/L 的含钒料液处理可降至5 mg/L 以下,并进行了间歇式提取实验。
Using primary amine N_(1923) as a mobile carrier,kerosene as membranesolvent,and N_(205) as surfactant the emulsion liquid membrane was studiedin the extraction of V(V).The optimat operating conditions were deter-mined.Under these conditions,the extraction ratio of V(V)was about99%.The transport mechanism was discussed.The experiments indicatethat the liguid membrane is capable of recovering vanadium from wastewater.
