Printing and dyeing wastewater is known for its high color intensity, complex composition, low biodegradability, making treatment a significant challenge in environmental protection. Dolomite natural mineral with abundant reserves can be effectively used as an adsorbent carrier. In this study, the dolomite loaded by Fe2O3 composites (DFC) was synthesized systematically characterized using XRD, SEM, TEM, BET, XPS, IR to evaluate structural surface properties. The adsorption performance of DFC on Congo Red (CR) then investigated. maximum amount CR 3790.06 mg⋅g−1, removal rate still stable at 97% after five cycles test, which demonstrated that exhibited exceptional efficacy regeneration capability. Fe3+ beneficial improve effect DFC. addition, type adsorption, kinetic calculations were performed, indicated Weber–Morris diffusion modeling study showed behavior influenced interplay many mechanisms. offers innovative method efficient utilization creating renewable materials dye remediation.
