Objective The widespread and excessive utilization of antibiotics and anti-tumor drugs has resulted in an increasingly grave scenario of water pollution induced by organic pharmaceuticals. This， in turn， has precipitated a series of deleterious ecological repercussions. Such a phenomenon has impelled the academic community and the environmental protection domain to accord significant attention to efficacious and sustainable methodologies for the elimination of antibiotics and anti-tumor drugs from the aqueous phase. Taking mitoxantrone hydrochloride， an anti-tumor drug， for example， due to its non-specific toxicity， upon its discharge into the natural environment， the residual pollutants pose a long-term menace to organisms and human health. Therefore， this study aims to develop efficient absorbents for the removal of anti-tumor drugs such as mitoxantrone hydrochloride.Method In this investigation， by directly calcining the precursor， Ferric Disodium Ethylenediaminetetraacetate， the iron-doped porous carbon materials were successfully prepared in one step. Subsequently， this material was applied to the experiment for the removal of mitoxantrone hydrochloride from water bodies. During the course of this research， the variances in the removal efficiency of mitoxantrone hydrochloride by iron-doped porous carbon materials under disparate calcination temperatures（200， 400， 600， 800 °C） were contrasted. Concurrently， multiple characterization techniques， such as scanning electron microscopy （SEM） and specific surface area analysis（BET）， were utilized to probe and analyze the microstructures and surface properties of iron-doped porous carbon materials under different calcination temperatures. Moreover， this study also systematically probed into the impacts of diverse adsorption conditions， including the dosage of the adsorbent material， the pH value of the solution， and the reaction temperature， on the adsorption efficiency of mitoxantrone hydrochloride by the iron-doped porous carbon material （C-Fe-600） obtained via calcination at 600 °C.Result The experimental outcomes reveal that when the dosage of C-Fe-600 is 0.8 g/L， the reaction temperature is 40 °C， and the pH value of the solution is 9， the removal efficiency of mitoxantrone hydrochloride by this material attains its peak. Further research uncovered that the C-Fe-600 material exhibits favorable recyclability， and in the actual treatment of wastewater， it can also effectively remove mitoxantrone hydrochloride present therein.Conclusion This fully demonstrates that C-Fe-600 is an outstanding and reusable adsorbent material， evincing promising feasibility and application prospects in practical environmental governance endeavors.
