{"doi":"10.5772/intechopen.99846","title":"A History of the Fenton Reactions (Fenton Chemistry for Beginners)","abstract":"A deceptively simple mixture, ferrous sulfate (FeSO4), hydrogen peroxide (H2O2), tartaric acid (C4H6O6), and water (H2O), initiated a century-long argument and a convoluted hunt to understand the oxidation mechanism(s) initiated by the combination of these components. Fenton’s discovery rallied a legion of scientists, including two Nobel Winners, to find an explanation for the chemistry discovered when a graduate student mixed a couple of random chemicals, producing a molecule that became purple in strong base. Those investigation uncovered three separate branches of iron/oxygen chemistry, the Hydroxyl Radical [HO•], the Ferryl-Oxo Ion [Fe = O]+2, and the Perferryl-Oxo Ion [Fe = O]+3. Today their uses include chemical modifications [either untargeted and random [HO•] or targeted and selective [Fe = O]+2, [Fe = O]+3 dehydrogenations and/or oxygen additions] to effective and green oxidation and mineralization of persistent organic wastes.","journal":"Biochemistry","year":2022,"id":280136,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":12,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9491,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":434981,"name":"Rafael Ovalle","orcid":null,"position":0,"is_corresponding":true}],"reference_count":115,"raw_metadata":null,"created_at":"2026-07-19T00:28:59.341002Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
