In recent years, the rapid development of industry has led to discharge large quantities pollutants, including harmful dyes, into water sources, thereby posing potential threats human health and environment. FeOCl biochar have their own shortcomings as a mediator in heterogeneous Fenton process. To make both materials useful, supported on bamboo (FeOCl/BC) was prepared by calcination using FeCl3·6H2O powder raw materials, composite’s catalytic activities were explored with acid orange II (AO-II) target pollutant. The degradation efficiency FeOCl/BC composites AO-II determined testing mass ratio BC, initial pH, temperature, H2O2 concentration, catalyst addition, addition coexisting inorganic anions, natural organic matter. increased activation generate •OH for removal accelerated cycle Fe3+/Fe2+. rate Fe1C0.2 composite 97.1% when BC 1:0.2 (Fe1C0.2), which higher than that pure components (FeOCl or BC) at pH = 6.1. Moreover, after five reuses, still showed high activity AO-II, 83.3% low loss. capture experiments active material mainly dominated •OH; however, •O2− h+ played minor roles. synthesized could be applied contaminants such efficiency.
