Synthesis of Fe3O4 poly(styrene-glycidyl methacrylate) magnetic porous microspheres and application in the immobilization of Klebsiella sp. FD-3 to reduce Fe(III)EDTA in a NOx scrubbing solution

► Poly(St-GMA) magnetic porous microspheres were synthesis with high magnetic contents. ► The MPPM was synthesized by surfactant reverse micelles and emulsion polymerization. ► The OA-MPPM was more suitable to immobilize FD-3 than the PEG-MPPM. ► The immobilized FD-3 had a good performance on Fe(III)EDTA reduction.
