Abstract

The separation and recovery of Fe(III) in heavy metal mixtures is a great challenge due to its strong ion exchange property. In this study, we developed a novel cinnamon-like blended fiber (PAN/PEG) using electrostatic spinning and dissolution post-treatment, which exhibited highly selective separation properties and satisfactory adsorption capacity for Fe(III). Owing to the preferential coordination of Fe(III) with both cyanide and hydroxyl groups, PAN/PEG possessed such excellent adsorption capacity as 1.12 mmol/g. Notably, the infinite selective separation coefficient between Fe(III) and other heavy metal ions (HMIs) achieved even from the octa-mixed metal systems. Furthermore, PAN/PEG demonstrated good anti-interference ability against coexisting inorganic salts. In addition, PAN/PEG was highly effective in removing lower concentration Fe(III) from complex PTA wastewater with super-high selectivity, which enabled the subsequent purification of Co(II) and Mn(II). Overall, PAN/PEG could be prepared and recovered facilely, and had great potential in the exclusive separation of Fe(III).

类肉桂混合纤维对Fe(III)的高选择性分离研究
铁(III)具有较强的离子交换特性,是重金属混合物中分离和回收的一大挑战。本研究采用静电纺丝和溶解后处理的方法制备了一种新型的肉桂类共混纤维(PAN/PEG),该纤维具有高度的选择性分离性能和对Fe(III)的良好吸附能力。由于Fe(III)与氰化物和羟基的优先配位,PAN/PEG具有1.12 mmol/g的优异吸附量。值得注意的是,即使在八元混合金属体系中,Fe(III)和其他重金属离子(hmi)之间也实现了无限的选择性分离系数。此外,PAN/PEG对共存无机盐表现出良好的抗干扰能力。此外,PAN/PEG对复杂PTA废水中低浓度Fe(III)具有超高选择性去除效果,从而实现Co(II)和Mn(II)的后续净化。综上所述,PAN/PEG制备方便,回收方便,在Fe(III)的纯分离方面具有很大的潜力。
