Abstract: A method for preparing an adsorbent for a skin aging diagnosis based on a body odor volatile marker according to an embodiment of the present disclosure comprises: forming a graphene oxide;polyaniline (GO;PANI) compound layer through an electrochemical polymerization reaction of an electrolyte including graphene oxide and an aniline monomer; forming a graphene oxide;polyaniline/zinc oxide nanorods (GO;PANI/ZNRs) composite layer by growing zinc oxide nanorods on the GO;PANI compound layer; and forming a graphene oxide;polyaniline/zinc oxide nanorods/zeolitic imidazolate framework-8 (GO;PANI/ZNRs/ZIF-8) composite layer by reacting the GO;PANI/ZNRs composite layer with a 2-methylimidazole (2-MI) solution.
