摘要: The presence of organic contaminants in industrial effluents is an environmental concern increasing global importance. One innovative technology for treating contaminated nanoscale zero-valent iron supported on biochar (nZVI/BC). Based Transmission Electron Microscopy, X-Ray Diffraction, and Brunauer-Emmett-Teller characterizations, the nZVI was well dispersed aggregation dramatically reduced. Methyl orange (MO) served as representative contaminant verifying effectiveness composite. Using decolorization efficiency indicator treatment effectiveness, doses nZVI/BC yielded progressively better results with 98.51% MO decolorized by 0.6 g/L composite at mass ratio 1:5. superior attributed to increase dispersion reactivity while contact area adsorption composites. Additionally, buffering function acid-washed could be favor maintaining nZVI. Furthermore, aging 30 day able maintain removal indicating that oxidation may delayed biochar. Therefore, represent effective functional material wastewater containing dyes future.
