Preparation, characterization of electrospun meso-hydroxylapatite nanofibers and their sorptions on Co(II)

- PVA/HA nanofibers could change into meso-HA nanofibers by calcination process.
- Sorption of Co(II) on meso-HA was strongly dependent on pH and ionic strength.
- Sorption kinetic data were well fitted by the pseudo-second-order rate equation.
- Sorption isotherms could be well described by the Langmuir model.
- Sorption process of Co(II) on meso-HA nanofibers was spontaneous and endothermic.
