摘要

摘要: 以葡萄糖为原料，采用水热法制备了多孔炭纳米球（PCNs）。以该多孔炭纳米球为吸附剂，研究其对水中四溴双酚A （TBBPA）的吸附性能。通过扫描电子显微镜、傅里叶红外光谱仪和热重分析仪考察了PCNs的结构及形貌特征。水分散性实验表明，PCNs能在水中均匀分散，且经12 h静置后可以自然沉降，有利于吸附后从溶液中分离。考察了吸附时间、温度、TBBPA浓度、溶液pH值以及盐度对吸附的影响。结果表明，PCNs对TBBPA具有良好的吸附能力，吸附量达到10.91 mg/g；吸附动力学过程可以用准二级速率方程描述，吸附等温线可用Langmuir方程拟合。溶液pH和盐度对吸附均有影响，中性环境有利于吸附的进行，PCNs是一种潜在的水处理材料。

Abstract: Porous carbon nanospheres (PCNs) were prepared by a hydrothermal method using glucose as the precursor. The structure and morphology of the PCNs were characterized by FT-IR, TGA and SEM. The PCNSs can be well dispersed in water and settle within 12 h, which is beneficial for separation from solutions. The adsorption of tetrabromobisphenol A (TBBPA) in aqueous solutions by PCNs was investigated. Results indicate that the maximum adsorption capacity of PCMSs for TBBPA is 10.91 mg/g at 293 K. The adsorption kinetics and isotherm are well described by a pseudo-second-order kinetic model and the Langmuir model, respectively. The adsorption is favorable under neutral conditions. PCNs is a promising adsorbent for water treatment.
