Abstract

Abstract

In this study, biochars were prepared by sewage sludge at 300, 400, 500, 600℃, respectively. The influence of preparation temperature on Cr(Ⅵ) adsorption by biochar was investigated through single factor static adsorption experiment. The results showed the positive effect of Cr(Ⅵ) adsorption along with increase of preparation temperature under 500 ℃, and negligible change within the preparation temperature range of 500~600 ℃. Differences of surface morphology and functional groups of biochars prepared by various temperature were characterized by SEM (scanning electron microscope), BET (Brunauer Emmett Teller) and FTIR (Fourier transform infrared), which were considered as the capital factor for diversity of adsorption. The results of isothermal model and kinetic fitting demostrated that the Cr(Ⅵ) adsorption by biochars as modality of monomolecular layer, physical-chemical composite adsorption; the experimental results showed that the optimal preparation temperature was 500 ℃. The theoretical adsorption capacity for Cr(Ⅵ) of biochar prepared under the condition of 500 ℃ reached 7.93 mg/g. The research conclusion could provide theoretical basis and practical support for recycling of municipal sludge.
