In this work, catalytic activity of natural chalcopyrite (CuFeS2) was improved by thermal activation. The modified used as efficient catalyst for degradation organic dye Rhodamine B (RhB) through advanced oxidation process (AOP). Effects dosage, H2O2 concentration, reaction temperature, solution pH, anions, and matter on the efficiency RhB were investigated. This study revealed that activation at 300°C changed chemical valency surface elements rather than transforming major phase chalcopyrite. Fenton-like significantly thermally activated could be obtained under broad pH showed high resistance to anions. Under optimal conditions 43.0 mM, 0.75 g/L, initial 4.0, temperature 25°C, reached 96.7% 50 min. Based rate constant kinetics, energy calculated 9 kJ/mol. Radical scavenging experiments electron paramagnetic resonance (EPR) technique demonstrated dominated generated hydroxyl radicals in chalcopyrite/H2O2 system. formation sulfates resulted from induced dissolved copper or iron ions, promoted facilitated reactive radicals. work provides an in-depth understanding mechanism behind enhance chalcopyrite, offering a theoretical basis utilizing minerals treatment wastewater towards cleaner production.
