8 Claims

1. A method for preparing an adsorbent for a skin aging diagnosis based on a body odor volatile marker comprising:

forming a graphene oxide;polyaniline (GO;PANI) compound layer through an electrochemical polymerization reaction of an electrolyte including graphene oxide having a content of more than 0 weight % and less than or equal to 8 weight % and an aniline monomer having a content of 18˜74 weight %;

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 having a content of 25˜77 weight %.
