Abstract : This study aims to combat and analyse marine ecosystems that are seriously threatened by microplastic pollution, emphasizing the urgent need for efficient remediation techniques. In this work, we introduce a novel ferrofluid technology method for removing microplastics from ocean water. We should selectively capture microplastics by magnetic attraction by creating a ferrofluid mixture with oils, and magnetite nanoparticles. Additionally, the incorporation of strong magnets into water samples should be prioritized to enhance the effective removal of microplastics, enabling easier separation, filtration, and purification of samples. This approach highlights sustainable practices by recycling and reusing recovered pollutants, in addition to demonstrating high efficiency and selectivity in microplastic extraction. However, the safe handling and disposal of hazardous materials is to be guaranteed by the responsible management of ferrofluids per local regulations in advance. This overlooked strategy demonstrates the potential for fusing cutting-edge technology with environmental stewardship to support cleaner and healthier ecosystems while providing a viable remedy for microplastic pollution in aquatic environments.
