Adsorption of bilirubin to magnetic multi-walled carbon nanotubes as a potential application in bound solute dialysis

► Magnetic MWCNTs could be dispersed in aqueous solution and isolated by a magnet. ► Magnetic MWCNTs showed high adsorption capacity and affinity for bilirubin. ► The adsorption of bilirubin to magnetic MWCNTs was thermodynamically spontaneous and followed the Langmuir model. ► Bilirubin could be removed from albumin solution by magnetic MWCNTs suspension in bound solute dialysis.
