  • 摘要: 利用廉价的农业废弃物油茶壳,以磷酸作为活化剂,料液比1:5(W:W),活化温度500℃,活化时间2 h条件下制备了油茶果壳炭,再经芬顿试剂10:1(N:N)进行改性,制备了新型的吸附材料.通过扫描电镜SEM观察吸附剂表面形貌,傅里叶红外光谱FT-IR分析其表面官能团,X-射线粉末衍射分析其晶型结构,N2吸附-脱附分析其比表面积大小及孔径分布.结果表明,羟基自由基改性材料孔隙结构表层部分被覆盖,不含铁矿物晶体,表面产生了大量的羟基、羰基、羧基基团,能够有效地改善油茶果壳炭的吸附效果; 油茶果壳炭改性前后比表面积分别为1244 m2·g-1、167 m2·g-1,平均孔径分别为3.284 nm和4.021 nm,说明材料孔道没有被堵塞.
    Abstract: Shell of camellia oleifera abel (COA) which is a cheap agricultural by-product was made into camellia oleifera shell carbon (COSC) by adding phosphate as a chemical activator with the ratio 1:5 (W:W) at 500℃ in 2 h. Modified COSC by Fenton's regent with the ratio 10:1 (N:N), and a new absorbent material was made.The surface of absorbent was observed by SEM through FT-IR to analysis the function group, also analysis the crystal structure by XRD, and analysis superficial area with pore size distribution by N2 absorption-desorption.In the result, the pore structure of hydroxyl radical modified material was covered without iron ore crystal. Large amount of hydroxyl, carbonyl and carboxyl group was generated to improve the modified COSC absorption capacity. When comparing with the BET surface area and average pore size of before and after modified COSC that were 1244 m2·g-1, 167 m2·g-1 and 3.284 nm, 4.021 nm respectively, which indicated the material channels were not blocked.
