  • 摘要: 利用农业废弃物稻壳经炭化、活化、酸洗、水洗和干燥等工艺制备出一种富含微孔和中孔结构的稻壳活性炭,其BET比表面积达886.3 m2/g。通过正交实验优化了稻壳活性炭对磷吸附条件,并在该条件下进行了吸附等温和吸附动力学实验研究。结果表明,稻壳活性炭对磷的吸附等温曲线能较好符合Langmuir模型(R2 = 0.9284)和Freundlich模型(R2 = 0.9208),由Langmuir线性拟合方程可得稻壳活性炭对磷饱和吸附量达6.93 mg/g;稻壳活性炭对磷的吸附过程可用准二级动力学方程描述(R2 = 0.9968),吸附速度较快,颗粒内扩散为该过程控速阶段。稻壳活性炭作为一种易得、廉价、高效的填料,在农村分散型污水生态处理技术中,具有良好的应用前景。
    Abstract: Powder activated carbon (PAC) with rich microporous structure was prepared from rice husks by carbonizing, activating, pickling, washing and drying, and its specific surface area (BET) was 886.3 m2/g. The adsorption process of PAC to phosphorus (P) was studied. The results showed that the adsorption isotherm could be described by both Langmuir model (R2 = 0.9284) and Freundlich model (R2 = 0.9208), and the saturated adsorption capacity reached 6.93 mg/g. The adsorption process of PAC to P could be described by pseudo second-order kinetic equation (R2 = 0.9968), and the rate of adsorption was under the control of intra-particle diffusion. PAC, as available, cheap and efficient matrix filler, has bright prospects in ecological treatment technologies of rural sewage.
