Abstract

Significant concerns have been raised over antibiotics pollution in aquatic environments in recent years. In this study, sorption of sulfamethazine (SMT) by novel graphene oxide-coated biochar nanocomposites (GO-BC) based on graphene oxide (GO) with bamboo sawdust biochar (BC) was investigated. In comparison with the original BC, the sorption capacity of GO-BC for SMT increased by 1.14 times. Sorption of SMT onto GO-BC was proved to be dominantly by chemisorption, and Freundlich isotherm described the sorption adequately. It was found that variation of pH and ionic strength obviously affected the sorption of SMT, and GO-BC had a good sorption effect on SMT at pH 3.0-6.0 and lower ionic strength. Obvious enhancement (by 30%) in sorption of SMT on GO-BC was observed, which might be attributed to the increase of functional groups on the surface of GO-BC. Moreover, the main sorption mechanism for SMT was π-π electron-donor-acceptor interaction, while auxiliary sorption mechanisms were inferred as pore-filling, cation exchange, hydrogen bonding interaction and electrostatic interaction. The results indicated that GO-BC sorption was an efficient way for the removal of SMT.

  • Huang et al. (2017) graphene oxide-coated biochar nanocomposite increased (O+N)/C ratio and O-C=O groups compared to pristine biochar; about 30% of sulfamethazine was adsorbed by GO-BC due to increasing surface functional groups.

    “In addition, the analysis showed that about 30% of SMT was adsorped by GO-BC due to the increasing surface functional groups.”
  • The specific surface area of GO-BC increased from 184.9 to 348.2 m2/g and the adsorption capacity of sulfamethazine was two times higher than that of original biochar.

    “Moreover, the specific surface area of GO-BC increased from 184.9 to 348.2 m 2 /g and the adsorption capacity of SMT was two times higher than that of the original BC.”
  • Adsorption of sulfamethazine on biochar and GO-BC was in good agreement with the pseudo-second-order model, indicating that SMT was removed by the chemisorption process.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
