采用磁性纳米功能化炭（MNP @C）和H2 O2、紫外光和超声波（US）强化同步吸附/氧化工艺处理纺织废水。吸附过程包括膜扩散和孔扩散两种作用机制。H_2O_2存在下，氧化降解对染料吸附有促进作用，其适宜性顺序为UV-芬顿> US-芬顿>芬顿。MNP @C/H2 O2/UV体系的催化活性为47%。对于UV-Fenton体系，经过5次循环后，染料的去除率达到94.8%，铁的浸出量最小。MNP @C对直接红16（DR 16）降解的催化活性顺序为PMS > PS > H2 O2。(C)2017年韩国工业和工程化学学会。Elsevier B. V.出版，保留所有权利。
Textile wastewater was treated using an enhanced simultaneous adsorption/oxidation process with magnetic nanoparticles-functionalized carbon (MNPs@C) and H2O2, UV and ultrasonic (US). Both film and pore-diffusion affect adsorption mechanisms were included in the adsorption process. The dye adsorption was enhanced by oxidative degradation in the present of H2O2 with the suitability in order of UV-Fenton > US-Fenton > Fenton. Catalytic potential of 47% was observed for MNPs@C/H2O2/UV system. For UV-Fenton system 94.8% removal of dye with minimal iron leaching was observed after 5 times of recycle. Increasing catalytic activity of MNPs@C on direct red 16 (DR16) degradation follows the order of PMS > PS > H2O2. (C) 2017 The Korean Society of Industrial and Engineering Chemistry.
