摘要：
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.
