▎ 摘　　要

NOVELTY - A zinc ferrite-chitosan/graphene oxide composite is obtained by crosslinking zinc ferrite magnetic particles and chitosan to obtain zinc ferrite-chitosan, and supporting zinc ferrite-chitosan on graphene oxide sheet. The mass ratio of zinc ferrite magnetic particles and chitosan is 0.83-1.66:3. The mass ratio zinc ferrite-chitosan and graphene oxide is 0.8-1.2:1. USE - Zinc ferrite-chitosan/graphene oxide composite used as adsorbent for separating fuchsine (claimed). ADVANTAGE - The zinc ferrite-chitosan/graphene oxide composite having excellent adsorption property is manufactured efficiently and economically by simple method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of zinc ferrite-chitosan/graphene oxide composite; and (2) usage of zinc ferrite-chitosan/graphene oxide composite as adsorbent for separating fuchsine.
