The rapid development of industry has led to heavy metal pollution becoming a significant environmental concern, with particular attention being focused on antimony pollution. China, as one of the world’s largest producers of antimony, faces potential threats to ecosystems and human health from this type of pollution. To address this issue, an innovative method for preparing new green functional materials was proposed in this study. An efficient and economical composite material (FCM) was developed, based on non-toxic chitosan loaded with the metal-organic framework (MOFs) and magnetic nano ferrosolferric oxide. This material was then used to adsorb Sb (III) in water environments. The effects of the mass ratio of chitosan to metal-organic frameworks (MOFs) denoted as MIL-100(Fe), ferrosolferric oxide nanoparticles (Nano-Fe3O4) to chitosan, reaction temperature, reaction time, and initiator concentration on the removal rate of Sb (III) were investigated. The results indicated that a mass ratio of 1:2:2 for Fe3O4, chitosan, and MOFs, an initiator concentration of 1.25 mmoL·L-1, a reaction time of 90min, and a water bath temperature of 60℃ resulted in a removal rate of Sb (III) from FCM reaching 96.8%. Characterization analysis revealed the rough and uneven surface of FCM, with numerous aggregated irregular particles and porous crystalline structures. In conclusion, FCM demonstrates effective removal of heavy metal antimony from water while exhibiting high environmental compatibility and sustainability.
