•The removal efficiency of n-MgFe2O4 for Co(II) ions was investigated.•Rapid removal efficiency was observed within 60min of contact time.•The kinetic data of Co(II) followed the pseudo-second-order model.•Thermodynamic studies revealed that the adsorption reaction was spontaneous.•Desorption study...
