摘要: 本文通过傅克反应制备了完全后交联反应树脂XC-01,并分别利用元素分析、红外光谱分析、N2吸附-脱附分析和扫描电镜分析对其进行表征分析.以水杨酸、没食子酸为研究对象,分析对比XC-01与国外进口树脂XAD-4的吸附性能差异,发现XC-01对水杨酸、没食子酸吸附容量分别达到XAD-4的4.96倍和7.23倍,具有较好的应用前景.进一步深入探究并总结pH、温度、时间等对XC-01吸附行为的影响规律,发现低温、酸性环境有利于树脂的吸附,吸附平衡时间在120 min;同时吸附容量存在水杨酸>没食子酸的规律,这主要与吸附质的亲水性和分子尺寸有关.Freundlich模型能够更好地模拟吸附过程,推测吸附过程以物理作用为主,为该类废水的无害化、资源化技术的开发与应用提供理论指导.Abstract: In this paper, hypercrosslinked resin XC-01 was synthesized by Friedel-Crafts reaction and characterized by elemental analysis (EA), Fourier-transformed infrared spectroscopy (FTIR), N2 adsorption-desorption analysis and scanning electron microscopy (SEM).XC-01 displayed much better adsorption performance than amberlite XAD-4 and its adsorption capacities towards salicylic acid and gallic acid were 4.96 and 7.23 times larger than those of XAD-4 respectively, which indicate good application prospect of XC-01. It was also found that low temperature and acidic environment were favorable for the adsorption and the resin reached equilibrium in a remarkably short time of 120 min. Compared to gallic acid, better adsorption capacity was achieved with salicylic acid as a result of low hydrophilicity and smaller molecular size of the adsorbate. Freundlich model could better simulate the adsorption process, suggesting physical interaction was the major adsorption mechanism.The research provides theoretical foundation for wastewater treatment and resource utilization.
