A new nano zero-valent iron (nZVI) material that generates acidic conditions in situ was prepared by grafting acid precursor onto diatomite. This new material was used in the evaluation of Bisphenol A (BPA) degradation by a Fenton-like process. The prepared material (M-nZVI-Da) exhibited a high removal efficiency (100%) of BPA under the natural pH conditions of the solution (pH ~ 5.75). The degradation of BPA using this new catalyst material follows a reaction pathway modelled on Fermi’s equation with predictable kinetic outcomes for increased temperature of reaction. Experiments demonstrate that the optimum starting concentration ratio of H2O2/sample is 200 mM/g-1 for efficient catalyst use. This study shows that nZVI materials with acid precursor are efficient catalysts for removal of BPA in solution.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
