“…Polymeric resins based on divinylbenzene copolymers such as poly (N-vinylpyrrolidonedivinylbenzene, poly (styrene-divinylbenzene) modified with amine, hypercrosslinked polymeric resin (MN200), Amberlite XAD-4, crosslinked poly-4-vinylpyridine and poly(methylmethacrylate-divinylbenzene) have been evaluated for removing phenolic compounds from wastewater [2,[5][6][7][8][9] . Although magnetic composite materials have a wide range of potential technological applications, such as water treatment, cell labeling, cell separation, enzyme immunoassaying and drug targeting, the evaluation of this type of material for extraction of phenolic compounds has not been sufficiently studied [10][11][12][13][14] . In our last work, we verified that it is possible to prepare micrometer-sized magnetic particles (NiFe 2 O 4 , CuFe 2 O 4 , CoFe 2 O 4 and MnFe 2 O 4 ), hosted on commercial Sty-DVB copolymers [10] .…”
