摘要

研究笋壳醋酸木质素(bamboo shoot shell acetic acid lignin, BSS-AL)对Cr(VI)的吸附性能和机制。通过批量吸附实验研究pH、BSS-AL添加量、接触时间和Cr(VI)的初始浓度对吸附过程的影响并建立吸附模型,利用傅里叶变换红外光谱(fourier transform infrared spectroscopy,FTIR)和X射线光电子能谱(X-ray photoelectron spectroscopy,XPS)比较吸附前后BSS-AL的官能团及元素组成来探究吸附机制。结果表明,BSS-AL能有效吸附重金属Cr(VI),在含Cr(VI)的体系中暴露240 min后,BSS-AL对Cr(VI)的清除率已超过97%,其动力学模型符合准二级动力学模型。BSS-AL对Cr(VI)的最大吸附量能达到14.908 mg/g,吸附等温模型符合Langmuir模型。FTIR和XPS分析技术阐释了BSS-AL吸附Cr(VI)的机制,即静电相互作用、离子交换和还原后再吸附。综上,BSS-AL在去除食品中的有毒重金属污染物Cr(VI)中具有很大潜力。

Abstract

This study aimed to evaluate the adsorption capacity and potential adsorption mechanisms of Cr (VI) by bamboo shoot shell acetic acid lignin (BSS-AL). The effects of pH, addition amount of BSS-AL, contact time and initial Cr(VI) concentration were studied through batch adsorption experiments. And the adsorption models were also been established. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were used to detect the functional groups and element composition of BSS-AL before and after adsorption in order to explore the adsorption mechanisms. The results showed that BSS-AL exhibited high-efficiency adsorption capacity of Cr (VI) and the removal rate of Cr (VI) could reach 97% in four hours. Furthermore, the pseudo-second-order kinetic model could be matched with the adsorption behavior over the whole range of adsorption process. Moreover, the adsorption of Cr (VI) by BSS-AL could be described well by Langmuir model and the maximum adsorption capacity reached 14.908 mg/g. The adsorption mechanisms could be explained by FTIR and XPS spectra: electrostatic interaction, ion exchange and re-adsorption after reduction. And BSS-AL has great potential to remove toxic pollutant Cr(VI) from food.
