摘要/Abstract

摘要：以杨梅单宁为原料，采用氯代的方法制备得到氯化单宁，再与氨基水杨酸反应得到氨基水杨酸改性单宁，然后经多聚甲醛交联得到氨基水杨酸改性单宁基树脂.采用傅里叶变换红外光谱仪对氨基水杨酸改性单宁基树脂的结构进行表征，并探究了溶液pH值、Ag(I)初始质量浓度、温度、时间等因素对氨基水杨酸改性单宁基树脂吸附性能的影响.结果表明，在温度为318 K、pH值为5.0、吸附时间为7 h、Ag(I)初始质量浓度为260 mg/L时，氨基水杨酸改性单宁基树脂对Ag(I)的最大吸附量可达239.6 mg/g，吸附过程符合Langmuir吸附等温模型和准二级动力学模型.这说明氨基水杨酸改性单宁基树脂具有良好Ag(I)吸附性能.

Abstract: The chlorinated tannins were prepared by chlorination of Bayberry Tannin with dichlorosulfoxide,then cross-linked with amino-salicylic acid to synthesize salicylic modified tannins,and then cross-linked with paraformaldehyde to obtain salicylic acid tannin-based resin.FTIR characterized the structure of the tannin-based resin.The effects of solution pH,initial concentration of Ag(I),temperature,and time on the adsorption performance were investigated.The experiments showed that the maximum adsorption of Ag(I) by the resin could reach 239.6 mg/g at the temperature of 318 K,pH of 5.0,and the initial concentration of Ag(I) of 260 mg/L.The adsorption thermodynamics indicated that this material's adsorption process of Ag(I) was in accordance with the Langmuir adsorption isotherm model and the quasi secondary kinetic model.It can be concluded that the amino-salicylic acid modified tannin-based resin has good Ag(I) adsorption performance.

Key words: amino-salicylic acid modified tannin-based resin, adsorption performance, Ag(I)
