Sorption characteristics of N-nitrosodimethylamine onto biochar from aqueous solution

Chen, Cuiping, Zhou, Wenjun, Lin, Daohui·2015·Bioresource Technology

Abstract

N-nitrosodimethylamine (NDMA) is an emerging carcinogenic disinfection by-product in water environment. Biochars utilized as sorbents for the removal of NDMA from aqueous solution, and the sorption characteristics and mechanism were investigate. Biochars were prepared from bamboo, rice straw and wood sawdust at 300-700°C. The pseudo-second-order model provided the best fit for the sorption kinetics of NDMA onto biochar and the sorption isotherms were described best with the Slips model. Biochar produced at 500°C removed NDMA from aqueous solution relatively efficiently, and the bamboo char demonstrated the best sorption potential among the three types of biochars. Solution chemistry such as pH and metal ions did not show obvious effect on NDMA removal. Three sorption mechanisms are suggested for NDMA sorption onto biochars, H-bond attraction between -N=O and the O-containing moieties, hydrophobic force between -CH3 and the ordered graphitic structure, and partition process of NDMA into the non-carbonization part of biochar.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sorption of organic contaminants on biochar occurs by pore-filling, diffusion and partitioning, surface hydrophobic and hydrophilic interactions, aromatic and cation-π interactions, electrostatic interactions, and hydrogen bonding, or by a simultaneous occurrence of these mechanisms.

    “occurs by: (a) pore-filling mechanisms (contributed by the majority of the surface area of biochar); (b) diffusion and partitioning mechanisms (effects of electrostatic interactions on the diffusion and equilibrium partitioning); (c) surface hydrophobic and hydrophilic inter-actions”

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.
