Biochar-induced Fe(III) reduction for persulfate activation in sulfamethoxazole degradation: Insight into the electron transfer, radical oxidation and degradation pathways
Abstract
Abstract In this study, the biochar (BC)-induced Fe(III) reduction for persulfate (PS) activation system was used for the first time in sulfamethoxazole (SMX) degradation. The apparent rate constant of the BC/Fe(III)/PS system was 31.3 and 8.2 times that of BC/PS system and Fe(III)/PS system, respectively. The carbon-centered persistent free radicals contained in BC acted as electron donors. Electron transfer occurred between the BC surface and Fe(III) successfully. Fe(II) was thus generated and played a key role for the subsequent PS activation. Scavenger quenching experiments and electron spin resonance spectrometry confirmed the presence of sulfate ( SO 4 · - ) and hydroxyl radicals ( HO · ), which brought about the efficient SMX degradation in the BC/Fe(III)/PS system. Furthermore, the frontier molecular orbital (FMO) theory and dual descriptor (DD) method were employed in predicting radical attacking sites of SMX. According to the results of theoretical computations and the experimental detection, degradation pathways of SMX in the BC/Fe(III)/PS system were deduced accurately. This study gives new insight into the possible mediatory roles of biochar in PS activation by transition metal ions. The BC/Fe(III)/PS system is a promising process for groundwater and soil remediation.

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.
