Organic contaminants have increasingly become a main threat to the water environment, necessitating novel methods for removing from polluted water. In this study, a kind of magnetic ethyl acetate microdrops (Fe3O4@KCC-1@EA) is fabricated for this purpose The KCC-1 shell of Fe3O4@KCC-1 nanospheres is a layer of silica with a dendritic fibrous structure. The ethyl acetate shell of the Fe3O4@KCC-1@EA microdrops provides them with the properties of an organic solvent. While the magnetic core makes them magnetically manipulable. Adding Fe3O4@KCC-1@EA microdrops to bisphenol A-polluted water allows the contaminants to be extracted into the ethyl acetate shell. These microdrops, saturated with bisphenol A, are then easily separated from the water phase with an external magnetic field, achieving a removal rate of over 98%. Besides bisphenol A, the Fe3O4@KCC-1@EA microdrops could also be employed to remove other organic contaminants. This method could provide a new pathway for water purification from organic contaminants.

磁芯支持的乙酸乙酯微滴用于去除水中的有机污染物
有机污染物日益成为水环境的主要威胁,需要新的方法来去除受污染的水。在本研究中,为此目的制备了一种磁性乙酸乙酯微滴(Fe 3 O 4 @KCC-1@EA)。Fe 3 O 4 @KCC-1 纳米球的 KCC-1 壳是一层二氧化硅,具有树枝状纤维结构。 Fe 3 O 4 @KCC-1@EA 微滴的乙酸乙酯壳使其具有有机溶剂的特性。而磁芯使它们可以通过磁性进行操纵。将Fe 3 O 4 @KCC-1@EA微滴添加到双酚A污染的水中,可以将污染物萃取到乙酸乙酯壳中。这些双酚A饱和的微滴随后可以通过外部磁场轻松地从水相中分离出来,去除率超过98%。除双酚A外,Fe 3 O 4 @KCC-1@EA微滴还可用于去除其他有机污染物。该方法可以为去除有机污染物的水净化提供新途径。
