Abstract

© 2020 Elsevier B.V. The total inactivation processes of two pathogenic bacteria, Escherichia coli and Enterococcus sp., by peroxymonosulfate (PMS) activation with CoFe2O4 nanoparticles was studied in real and simulated wastewater matrices. The catalyst was prepared by solvothermal method and characterized by means of powder X-ray diffraction and Transmission Electron Microscopy. It shows an excellent heterogeneous catalytic activity for PMS activation, easy separation, acceptable reusability and negligible leaching. A systematic study for the determination of optima catalyst and PMS dosages (0.05 g/L CoFe2O4 and 0.2 mM PMS) were investigated under UV-A radiation and darkness for an initial bacteria concentration of 106 CFU/mL. Scavenging experiments using methanol and TBA were performed to confirm that both, sulfate (SO4•-) and hydroxyl radicals (HO•), are involved in the inactivation process. A plausible mechanism reaction was proposed for UV-A and darkness and a Double Weibull mathematical model seems to fully describe the kinetic inactivation of both bacteria. The use of low catalyst and PMS concentrations concomitantly to the high efficiency showed for the total inactivation of wild bacteria in darkness makes this process suitable to be the last stage in a full wastewater treatment plant.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal CHEMICAL ENGINEERING JOURNAL due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2020, it was in position 4/143, thus managing to position itself as a Q1 (Primer Cuartil), in the category Engineering, Chemical. Notably, the journal is positioned above the 90th percentile.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 2.52. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 3.22 (source consulted: FECYT Mar 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2026-04-27, the following number of citations:

  • WoS: 71
  • Scopus: 75
  • Open Alex: 57

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-27:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 59.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 59 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 6.
  • The number of mentions on the social network X (formerly Twitter): 8 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/95444/

As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of

  • Views: 16
Continuing with the social impact of the work, it is important to emphasize that, due to its content, it can be assigned to the area of interest of ODS 6 - Clean water and sanitation, with a probability of 87% according to the mBERT algorithm developed by Aurora University.
