钠基膨润土对铕离子的吸附性能研究

Study the Adsorption Characteristics of Na-bentonite for the Eu^(3+) Ion

在静态条件下,研究了钠基膨润土对稀土元素铕离子的吸附性能。结果表明,钠基膨润土对铕离子有较强的吸附性能,pH是影响吸附的主要因素,吸附平衡数据符合Langmuir模型,讨论了钠基膨润土处理含金属稀土废水的可行性。用神经网络模拟了钠基膨润土对铕离子的吸附。

In the static condition,the adsorption performance of Na-bentonite on rare earth elements of the Eu3＋ ion was studied.The results showed that Na-bentonite on Eu3＋ ion had strong adsorption performance,pH was the main factor of influence adsorption,and adsorption balance data fit Langmuir model,and the feasibility of Na-bentonite to dispose of wastewater containing rare earth metal was discussed.Neural Network was used to simulate the adsorption of Na-bentonite on Eu3＋ ion.
