Study on the treatment of p-nitrofluorobenzene wastewater by activated carbon fiber

Zhao De-ming

Abstract

Activated carbon fiber (ACF) was used to treat p-nitrofluorobenzene (PFNB) wastewater. Adsorption isotherm and dynamic adsorption breakthrough curve are determined. Influencing factors for adsorption efficiency such as pH, temperature and adsorption time had been studied. The results indicated that pH had scarcely effect on adsorption efficiency between 3 and 9, adsorption efficiency decreased slightly with increase of temperature and adsorption time presented optimum value as the best adsorption time 5 min. ACF regenerated by steam had not much difference in adsorption efficiency through 4 cycles. Adsorption capacity of ACF for PFNB was large, adsorption rate was fast and regeneration condition was moderate.
