The experimental data showed that the experimental group (CT) with Fe₂(SO₄)₃ had a better degree of humification than the control group (CK). The humic substances (HS) content was 10% higher in CT (23.94 mg·g^-1) than in CK (21.54 mg·g^-1) in the final. Fe (III) contributed significantly to the formation of free radicals in HS. The amount of H₂O₂ in CT increased to 74.8 mmol·kg^-1, while CK was only 46.5 mmol·kg^-1. The content of semiquinone free radical was 10.32 × 10¹¹ spins/mm³ in CT, 5.11 × 10¹¹ spins/mm³ in CK in the end. Several iron-reducing bacteria were detected in composting, among which Paenibacillus was dominant. The above findings suggested that the application of Fe₂(SO₄)₃ enhanced the iron reduction synergistic quinone redox cycling and promoted the generation of free radicals during the humification of composting.23:T5f7,
