Abstract

Water pollution from industrial sources presents a significant environmental challenge due to the presence of recalcitrant organic contaminants.

Overview

AI snapshot

Written from the paper’s full text.

TL;DR

This overview reviews combining adsorption with Fenton oxidation for removing recalcitrant organic pollutants from water, arguing that adsorption pre-concentrates pollutants and supports catalysts to improve degradation. It surveys carbon-based materials, MOFs, and minerals/clays across medical, industrial, and urban wastewater applications.

Key findings

  • The synergy arises because adsorption captures pollutants via ion exchange, electrostatic interactions, hydrophobic attractions, π–π stacking, hydrogen bonding, and/or van der Waals forces, while also accelerating electron transfer and Fe(III)/Fe(II) redox cycling in Fenton systems. In one cited study, homogeneous and heterogeneous Fenton alone gave 79% and 54% decolorization with 59% and 33% COD removal, respectively; adding adsorption raised toxicity reduction to 95% and decolorization to 90%.
  • Support materials include activated carbon, graphene, carbon nanotubes, graphitic carbon nitride, biochar, MOFs, and minerals/clays. Reported examples include magnetic activated carbon degrading over 90% of 4-chlorophenol within an hour with >80% removal over five regeneration cycles; Fe3O4/RGO-2 with a maximum methylene blue adsorption capacity of 163.83 mg g−1 and complete MB degradation within 60 minutes; rGO/Fe NPs achieving 99.8% mitoxantrone removal at neutral pH; and Co0.8Fe0.2N-NC being 2.9 times more effective than traditional Fenton systems and 25.2 times more than conventional photocatalytic systems.
  • Applications span medical, industrial, and urban wastewater. For medical wastewater, avocado seed activated carbon plus solar photo-Fenton degraded fluconazole up to 80% and the remaining eight drugs in a mixture up to 99%; an iron–clay–cyclodextrin composite adsorbed and oxidized more than 65% of long-chain PFAS within 10 minutes.
  • The review concludes that future work should develop new adsorbent/catalyst composites, optimize conditions such as pH, temperature, and dosage, test complex water bodies, and advance economic large-scale technologies.

Methods

  • Design: narrative review/overview; the paper states that no new data were collected or analyzed. It focuses on non-biodegradable organic compounds and excludes heavy metals due to limited space and an existing recent review in that field.
  • Scope: mechanisms of Fenton oxidation and modified Fenton processes (photo-Fenton, electro-Fenton, photo-electro-Fenton), synergistic adsorption–Fenton effects, support materials (carbon-based materials, MOFs, minerals/clays), and applications in medical, industrial, and urban wastewater; the review contains 105 references.
  • Analysis: narrative synthesis with tables listing reported graphene/carbon nanotube supports and MOF-based supports with target pollutants, operational conditions, adsorption mechanisms, and Fenton mechanisms; no systematic search protocol or meta-analysis is described.

Limitations

  • Paper-stated: the review is limited to non-biodegradable organic pollutants and does not cover heavy metals such as Cr, Hg, Cu, and Pb. It also states that future study is needed on new adsorbent/catalyst composites, optimal catalytic conditions, complex water bodies, and economic large-scale application.
  • Paper-stated: the mechanism of the Fenton reaction still has disputes, although most scholars support the strong oxidizing role of ·OH.
  • Evident from the text: as a narrative overview, it compares performance numbers from heterogeneous studies conducted under different pollutants, catalysts, pH values, H2O2 doses, and reaction times, without a systematic quality assessment or quantitative meta-analysis.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Figure 2 credits a 1991 source with a 2020 copyright

    Minor

    The Figure 2 caption attributes the reproduced figure to Najm et al.35 with a 2020 copyright, but reference 35 is dated 1991.

  • Fe3O4/CeO2 study is attributed to a silica reference

    Minor

    The metal-oxides section attributes a mesoporous Fe3O4/CeO2 composite to Liu and colleagues at reference 87. Reference 87 instead describes an iron-containing mesoporous silica material.

  • Abstract understates the number of references

    Minor

    The abstract says the review contains 105 references, but the numbered reference list extends to 108.

  • Sulfadiazine and sulfamerazine names conflict for the same study

    Minor

    The biochar discussion calls the pollutant in Deng et al.'s study sulfadiazine, while its Figure 6 caption calls it sulfamerazine. Both passages describe the B@Ni-F cathode.

  • Table 2 and text cite different sources for FeNi-BDC

    Minor

    Table 2 assigns FeNi1/15-BDC to reference 44, while the discussion attributes the FeNiX-BDC study to Wu et al. at reference 30. Reference 44 is listed as a study of CoFeN-NC materials.

  • Ciprofloxacin study conflicts with its cited reference

    Minor

    The text describes reference 66 as a corncob-biochar study removing ciprofloxacin. Reference 66 is titled as a study of Taihu blue algae-derived biochar removing chelated nickel, so the stated example does not match its cited source.

  • Table 2 and text cite different sources for Co0.8Fe0.2N-NC

    Minor

    Table 2 assigns Co0.8Fe0.2N-NC to reference 17, whereas the discussion assigns that material to Miao et al. at reference 44.

  • Fenton by-products described as both absent and polluting

    Minor

    The introduction says the Fenton reaction produces no harmful by-products, whereas the mechanism section says a homogeneous Fenton reaction produces iron mud that causes secondary pollution.

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.

A language model drew the claims from the paper on 2026-11-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
