摘要:
采用蒸发诱导自组装制备磁性介孔材料,用TEM和VSM进行测试表征其性能,研究磁性介孔材料的结构和磁性能。该磁性介孔材料与H2O2组成非均相Fenton体系,用于染料废水的典型代表亚甲基蓝的脱色,研究其降解动力学。结果表明:其降解符合一阶动力学方程,在最优条件下,亚甲基蓝能够快速降解。此材料能够快速进行磁性分离,多次重复利用,有望作为催化降解染料废水的理想催化剂。
Abstract:
Magnetic mesoporous composites were synthesized by evaporation induced self-assembly. These materials were characterized by TEM and VSM to conduct a study on their structure and performace. The heterogeneous Fenton system was made up of magnetic mesoporous composites and H2O2, and was used to decolorize methylene blue, as typical representative of dyes wastewater to study the degradation kinetics of methylene blue. The results showed that the degradation mechanism was reasonably consistent with one order kinetic equation. Methylene blue was quickly degraded under the optimal conditions. This material can be quickly separated from the solution by magnetic field. Therefore, it can be reused for many times. It can be ideal catalyst for the degradation of dye wastewater.
