Immobilization of horseradish peroxidase by electrospun fibrous membranes for adsorption and degradation of pentachlorophenol in water

► HRP-EFMs were successfully prepared by emulsion electrospinning. ► HRP-EFMs can adsorb and biodegrade pentachlorophenol (PCP). ► The adsorption and degradation process of PCP was obviously influenced by pH. ► Humic acid decreased the adsorption capacity of PCP on EFMs. ► HRP immobilized on membranes shows better stability than free HRP.
