碳柱撑磁性膨润土催化降解焦化废水的研究

Applications of Fe_3O_4-C-MMT for Removal of Coking Wastewater

鉴于膨润土具有良好的吸附性,制备磁性膨润土,构建碳柱撑磁性膨润土/H_2O_2芬顿体系,以苯酚溶液模拟焦化废水进行催化降解实验,效果良好。重复使用5次以后,苯酚去除率仍可达到87.64%。证明碳柱撑磁性膨润土/H_2O_2芬顿体系有良好的吸附性和稳定性。

Bentonite was employed Fenton system of Fe_3O_4-C-MMT/H_2O_2 by modified solvothermal method. Simulated coking wastewater with phenol solution and found that its catalytic degradation of phenol has a good effect. After reused for 5 times by magnetic separation, the system still show a removel rate of 87.64%. The results imply that Fe_3O_4-C-MMT/H_2O_2 possessed good catalytic and stability.
