Recently, the appearance of microplastic particles has come under increasing public scrutiny. Microplastics cannot be completely decomposed, and they have a negative impact on the environment, human health, and the health of other living beings. Namely, the digestive system of the organism cannot digest microplastics, which represents a health risk for the ecosystem. Microplastics can bind chemicals from the environment, as well as bacteria and microbes that then create a biofilm. It is precisely for this reason that the problem of microplastics should be taken seriously, because if microplastics reach the human body, they can release toxic compounds as well as the microbes bound in it, damaging human health. In order to remove microplastics, there are several solutions, of which the extraction of microplastics with ferrofluids is presented in this paper. Ferrofluids represent a very strong magnetizing liquid composed of a liquid medium, containing solid magnetic particles of very small size, colloidally dispersed in a liquid carrier. The removal of microplastics with ferrofluids is very effective because even the smallest particles of microplastics can bind to the ferrofluid and be removed using a magnet. In this work, ferrofluid based on synthetic oil and six solutions of microplastic particles (polystyrene (PS) and polyvinyl chloride (PVC)) in the size range from slightly less than 300 μm to 500 μm were used. The microplastic removal technique with ferrofluid has been proven to be effective and fast. Polystyrene particles had generally better removal efficiency than polyvinyl chloride particles. It was also found that larger particles of 355-500 μm are easier to extracted than smaller particles of less than 300 μm.
