In this paper, magnetically recyclable Fe-doped lithium ion sieves (LFMO) with enhanced structure stability were synthesized using a solid state reaction method. The structure, adsorption capacity, dissolution loss and magnetic properties of as-prepared un-doped lithium ion sieve (LMO) and LFMO were characterized and compared. The results show that the as-prepared Fe-doped lithium ion sieves presented a dissolution loss of 0.26% and 0.10% (decrease about 90%) for Mn3+ and Fe3+, respectively, and adsorption capacity of 30.6 mg g(-1) (decrease about 15%). Furthermore, LFMO could be easily recycled with a magnet, and the adsorption capacity of reused LFMO could be 20.7 mg g(-1) after five adsorption-desorption cycles.
