DOI:
https://doi.org/10.51252/reacae.v4i1.802Keywords:
contaminants, efficiency, electrodes, electrochemistry, removalAbstract
This review article presents a bibliometric analysis of 3146 scientific articles extracted from the Scopus database, using the keywords “Wastewater Electrocoagulation”. The selection covered publications from 1975 to 2024, distributed in 715 sources and with the collaboration of 7876 authors. The VosViewer and Bibliometrics programs were used to carry out the analysis. In VosViewer, a minimum threshold of 12 occurrences per keyword was used, selecting 133 of the 4994 keywords registered using the normalized association method. These 133 terms were organized into 8 clusters, each analyzed according to recent advances in electrocoagulation reactor configurations, types of electrode materials, and pollutant removal efficiency in both domestic and industrial wastewater. The study focused on analyzing the evolution of publications on electrocoagulation and highlighting recent advances in pollutant removal using this technology. Through cluster analysis, a comprehensive view of current research was obtained, which allowed the identification of the most innovative and emerging areas of this technology. In addition, different methods and materials were evaluated to improve the efficiency of the process.
