This　study　introduced　a　novel　catalyst,　Cu-Fe@CTS　(Chitosan)-ATP　(attapulgite),　which　distinguished　itself　from　traditional　Fenton-like　catalysts　by　effectively　degrading　pollutants　across　a　broad　pH　range.　This　catalyst　achieved　impressive　degradation　rates　of　200　mg　L　-1　of　FA　(Fulvic　acid),　reaching　97　%　at　pH　=　3,　96　%　at　pH　=　7,　and　95　%　at　pH　=　10.　The　catalyst　＇s　enduring　effectiveness,　with　FA　removal　rates　marginal　decrease　to　94　%　at　pH　=　3　after　ten　cycles,　showcased　its　sustained　catalytic　activity.　The　underlying　mechanism　was　attributed　to　a　synergistic　interaction　facilitated　by　the　addition　of　Cu　2+　and　Fe　3+　into　ATP　＇s　framework,　which　generated　a　M　1　-O　-M　2　structure.　Experimentation　and　analysis　revealed　a　dynamic　electron　transfer　mechanism　within　the　M　1　-O　-M　2　structure.　Moreover,　the　catalyst　proved　to　be　highly　effective　in　treating　real　wastewater-leachate　concentrate,　underscoring　its　potential　for　environmental　remediation　across　diverse　pH　conditions.　This　research　laid　the　groundwork　for　expanding　the　pH　applicability　of　catalysts,　opening　new　pathways　for　advanced　environmental　clean-up　strategies.
