Abstract

ABSTRACT Biochars derived from chicken manure were prepared by anaerobic pyrolysis at 200°C, 400°C 600°C, and 800°C (referred as CBC200, CBC400, CBC600 and CBC800, respectively). The results indicated chicken manure biochars (CBC) prepared at higher temperatures exhibited higher aromaticity. The kinetics and isothermal equilibria of Cd(II) adsorption onto CBC were well fitted using the pseudo-second-order kinetic model and Langmuir model. The adsorption process was able to achieve equilibrium at 720 min and the maximum Cd(II) adsorption capacities of CBC produced at 200°C–800°C were 45.50–52.02 mg g –1 . The spectroscopic surface chemistry analyses using scanning electron microscopy with transmission electron microscopy, Fourier-transform infrared spectroscopy, 13 C nuclear magnetic resonance and Raman spectra indicated that the adsorption mechanism consisted of pore filling, complexation, precipitation and C-p interaction. Therefore, CBC could employ as an effective agent for the remediation of Cd contaminated water.

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.
