PAN基弱碱性离子交换纤维对钒的吸附性能研究
|
摘要
以一种PAN基弱碱性离子交换纤维为材料,研究了其对钒的吸附性能.静态吸附条件下,对比了两种功能基纤维(氢氧型、氯型)对钒吸附和再生性能的影响;探讨了p H、温度、吸附时间、钒溶液浓度对氯型纤维吸附性能的影响;考察了氢氧化钠解吸纤维的最佳浓度.动态吸附条件下,研究了温度、流速对纤维吸附钒的影响.实验结果表明:氯型纤维比多胺型纤维更稳定;氯型纤维在p H值为6～8时吸附性能最好,温度越高吸附量越大,反应6 h时吸附达到一种动态平衡,饱和离子吸附量为294 mg/g,钒的去除率达到98%以上.用0. 5 mol/L的氢氧化钠进行解吸,解吸率98. 02%以上.
A kind of PAN-based weak alkaline ion exchange fiber was synthesized to remove forvanadium. The adsorption and regeneration performance of two different types of functional groups of ionexchange materials were compared. Effects of p H,temperature,time,and the concentration of vanadiumon fiber saturated adsorption amount were investigated. The optimal concentration of sodium hydroxide for desorption the fiber was discussed. The results showed that the static adsorption capacity of Cl-form fiber were more superior; The maximum adsorption capacity( 294 mg/g) was obtained under pH 6 ～ 8 and adsorption capacity increased with the increase of temperature; the adsorptive equilibrium can be achieved with in 6 hours,and the removal ratio for Vanadium was more than 98%. The desorption rate of the fiber was above 98. 02%,when the concentration of desorption solution( sodium hydroxide) was 0. 5 mol/L.
