摘要

γ-CD为配体,KOH作为金属离子,通过KH580偶联合成环境友好型的环糊精金属有机框架材料(γ-CD-MOFs-SH)用于吸附水环境中痕量Hg(Ⅱ)。通过扫描电镜、傅里叶红外光谱仪、粉末X射线衍射仪及差示扫描量热仪对其结构和形貌进行表征。研究了实验参数对γ-CD-MOFs-SH吸附性能的影响,结果表明,利用拟二阶动力学模型和Langmuir等温吸附方程模型,可以很好地阐明Hg(Ⅱ)的吸附过程,理论上最大吸附能力高达208mg/g。此外,γ-CD-MOFs-SH在经过5次循环再生实验,吸附率仍达第一次的80%以上,具有优异的可再生吸附性能。

Abstract

With γ-CD as the ligand and KOH as a metal ion,a eco-friendly water-insoluble γ-cyclodextrin polymer (γ-CD-MOFs-SH) coupled by KH580 was obtained for adsorption Hg(Ⅱ).The scanning electron microscopy (SEM),Fourier infrared spectroscopy (FT-IR),powder X-ray diffraction apparatus (XRD) and differential scanning calorimeter (TGA) were used to characterize the structure and the morphology of composite materials.The effect of experiment parameters on the adsorption performance was investigated.The results showed that the adsorption process of Hg(Ⅱ) was well clarified by pseudo-second-order kinetic model and Langmuir model.The theoretical maximum adsorption capacity was as high as 208mg/g.Additionally,the adsorption capacity of γ-CD-MOFs-SH still retained over 80% of the original capacity after 5 cycles of regeneration test,which exhibited an excellent regenerative adsorption performance.
