In summary, Fe3O4/GO/CS composite was prepared by a facile and novel route,
and used as magnetic absorbent for protein enrichment study successfully.
Protein cytochrome c (Cyt c) was chosen as model target to evaluate the adsorptive property of Fe3O4/GO/CS.
The adsorption achieved equilibrium in a short time about 40 min suggested thatFe3O4/GO/CS showed fast adsorption rate.
The adsorption date could fit the Langmuir model
