摘要

采用静电纺丝法制备聚丙烯腈(PAN)纳米纤维膜，再以乙二胺为改性剂对PAN纳米纤维膜进行化学处理，制备出具有氨基的改性PAN纳米纤维膜(PAEA). 通过扫描电镜(SEM)、红外光谱(FTIR)、水接触角等对其物理化学性质进行表征并研究其对重金属离子Cr(VI)的吸附能力. 结果表明：PAN在水浴温度95 °C，水热时间2 h条件下改性后，纤维直径明显变粗且有一定的弯曲. 由FTIR分析发现改性后的PAN在3050 ~ 3300 cm

−1

范围内出现了特征峰，并且水接触角减小为44.7°，说明成功地将PAN纳米纤维膜改性为含有亲水性―NH

基团的PAEA纳米纤维膜. 除铬实验表明：在pH = 2时，吸附约10 h后达到最佳除铬效果，吸附量可达175.94 mg/g. 这种膜材料在使用后经稀NaOH溶液洗涤后，能够重复使用，循环4次后仍能保持70%左右的去除率，在处理重金属离子方面具有非常大的潜力.

Abstract

Electrospun nanofiber membrane of polyacrylonitrile (PAN ENMs) was chemically modified by reacting with ethylenediamine to make it into amino-functionalized on its surface

denoted as PAEA ENMs. The effects of ethylenediamine concentration

reaction temperature and reaction time of the hydrothermal process on the conversion of the cyano group and the adsorption capacity of the resulted nanofiber membranes were studied systematically. Scanning electron microscopy (SEM)

Fourier transform infrared spectroscopy (FTIR) and water contact angle test were used to characterize the physicochemical properties of PAEA ENMs. The results showed that PAEA nanofibers swelled and bended to a certain degree after hydrothermal treatment at 95 °C for 2 h

and the net-like structure of the membrane was well maintained. On the FTIR spectra

the peaks around 3300 - 3500 cm

−1

were ascribed to the typical absorption of ―NH

group. Water contact angle decreased from 114.5° for PAN ENMs to 44.7° for PAEA ENMs. All these suggest that PAEA ENMs was fabricated successfully. In order to investigate the netal ions removal performance through adsorption on the PAEA ENMs

a variety of Cr(VI) adsorption experiments were carried out and the adsorption kinetics and adsorption isotherms analized. The results showed that the adsorption capacity of PAEA ENMs was as high as 175.94 mg/g at pH = 2

and the adsorption equilibrium can be reached within 8 h. This is mainly due to the protonation of ―NH

groups under the acid condition

which is benefit for adsorbing negative HCrO

–

. The adsorption behavior fitted to the pesudo-second order kinetics and Langmuir isotherm adsorption model. Moreover

the PAEA ENMs can be reused after being washed with dilute NaOH solution separated from water. About 70% of its initial adsorption capacity was retained after four recycled use. Therefore

this PAEA ENMs has a high recyclability and is promising material for heavy metal ions adsorption.
