D401螯合树脂除氟方法及工艺研究

通过实验讨论了一种基于配体交换原理的新型改性D401除氟剂的除氟效果,实验表明该除氟剂的除氟容量可达3.8mg/g以上,除氟剂对水中F-有很高的选择性,不会对水中的其它离子产生影响,再生效果较好,除氟效果稳定。在实验的基础上给出了该方法的初步工艺设计思路,为该方法在实际中应用提供了参考思路。

Study on Defluorining Methods and Techniques of Modified D401 Chelating Resin

Through testing, this paper discusses on the defluorining effect of modified D401 chelating resin based on the part exchanging principle. Tests show that this defluorining agent, which has a high defluorining capability of more than 3.8mg/g, has high selectivity to F-and has no influence on the other ions in water, and has a stable defluorining effect and can be easily regenerated. Furthermore, this paper provides the idea of preliminary technological design of this method based on the tests, offering a reference for the application of this method in practice.
