摘　　要：采用硼元素对丑橘皮进行硼化处理,探究其对亚甲基蓝的吸附性能,通过FTIR、SEM、XRD和TEM等技术对普通生物炭和硼化生物炭进行表征,通过静态吸附考察MB初始浓度、吸附剂用量、pH、盐浓度、吸附时间等条件对结果的影响,并确定该吸附过程的吸附动力学、吸附等温线和吸附热力学。结果表明,硼化生物炭具有良好的多孔结构;含有大量含氧基团,对MB的吸附容量为134.87 mg/g;对MB的吸附等温线符合Langmuir模型,Q_(m)最高可达192.76 mg/g;盐浓度对吸附影响不大。The boron element was used to boronize the orange peel to explore its adsorption performance for methylene blue.The ordinary biochar and boronized biochar were characterized by FTIR,SEM,XRD and TEM.The effects of MB initial concentration,adsorbent dosage,pH,salt concentration,adsorption time and other conditions on the results were investigated by static adsorption,and the adsorption kinetics,adsorption isotherm and adsorption thermodynamics of the adsorption process were determined.The results showed that the boronized biochar had a good porous structure.It containsed a large number of oxygen-containing groups,and the adsorption capacity of MB was 134.87 mg/g.The adsorption isotherm of MB conformed to the Langmuir model,and the Q_(m)was up to 192.76 mg/g.The salt concentration had little effect on the adsorption.
