Zusammenfassung:	The present invention relates to a method of preparing a gadolinium-graphene oxide composite, a gadolinium-graphene oxide composite prepared by the same, and an adsorbent for removal of arsenic, including a gadolinium-graphene oxide composite. The method of preparing a gadolinium-graphene oxide composite comprises the following steps: preparing graphene oxide; preparing a mixture by mixing the grapheme oxide with gadolinium (III) nitrate hexahydrate (GdN_3O_9 · 6H_2O); preparing a gadolinium-graphene oxide composite by making the mixture react in a basic environment; and washing and drying the gadolinium-graphene oxide composite. 본 발명은, 그래핀 옥사이드를 제조하는 단계, 가돌리늄 나이트레이트 헥사하이드레이트(Gadolinium(III) nitrate hexahydrate(GdNO·6HO))를 상기 그래핀 옥사이드와 혼합하여 혼합물을 제조하는 단계, 상기 혼합물을 염기성 환경에서 반응시켜 가돌리늄-그래핀 옥사이드 복합체를 형성하는 단계 및 상기 가돌리늄-그래핀 옥사이드 복합체를 세척 및 건조시키는 단계를 포함하는 가돌리늄-그래핀 옥사이드 복합체의 제조방법, 이에 의해 제조된 가돌리늄-그래핀 옥사이드 복합체 및 가돌리늄-그래핀 옥사이드 복합체를 포함하는 비소 제거용 흡착제에 관한 것이다.
