摘要

单宁与多聚甲醛交联合成单宁酚醛聚合物，再以环氧氯丙烷为交联剂，将单宁酚醛聚合物与纤维素通过反相悬浮交联制备球形聚合单宁-纤维素树脂。通过傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）对球形聚合单宁-纤维素树脂的结构进行了表征，并考察了球形聚合单宁-纤维素树脂对盐酸小檗碱的吸附性能。结果表明，球形聚合单宁-纤维素树脂具有多孔的结构，树脂网络中含有大量的酚羟基；球形聚合单宁-纤维素树脂对盐酸小檗碱具有较好的吸附性能，当盐酸小檗碱浓度为600 mg·L-1、吸附温度为298 K时，最大饱和吸附量可达245.92mg·g-1；球形聚合单宁-纤维素树脂对盐酸小檗碱的吸附过程符合Langmuir吸附等温模型和准二级吸附动力学方程，热力学研究数据表明球形单宁-纤维素树脂对盐酸小檗碱的吸附是一个自发放热的物理吸附过程。该树脂在分离提纯生物碱方面具有潜在的应用前景。

Abstract

Tannin was crosslinked with paraformaldehyde to prepare tannin-phenolic polymer. The spherical poly(tannin)-cellulose resin was synthesized by inversing suspension cross-linking reaction of tannin-phenolic polymer and cellulose with epichlorohydrin as crosslinking agent. The spherical poly(tannin)-cellulose resin was characterized by infrared spectrum(FTIR) and scanning electron microscopy(SEM)

and the adsorption properties of spherical poly(tannin)-cellulose resin for berberine hydrochloride were evaluated. The spherical poly(tannin)-cellulose resin has a porous structure and a large amount of phenolic hydroxyl groups in polymer network. The spherical poly(tannin)-cellulose resin has high adsorption capacity for berberine hydrochloride

the maximum adsorption capacity of berberine hydrochloride on spherical poly(tannin)-cellulose resin was 245.92 mg·g-1 when the initial concentration of berberine hydrochloride was 600 mg·L-1 at 298 K. The adsorption isotherms and kinetics of spherical poly(tannin)-cellulose resin for berberine hydrochloride can be well fitted by the Langmuir equation and pseudo-second-order model

respectively. The data of thermodynamic analysis suggest that the adsorption for berberine hydrochloride on spherical poly(tannin)-cellulose resin was a spontaneous and exothermic physical adsorption process. The spherical poly(tannin)-cellulose resin has a potential application prospect in the field of the separation and purification of alkaloids.
