The present invention relates to a preparation method of a biomass-based adsorbent for removing a radionuclide or a heavy metal, a biomass-based adsorbent prepared thereby, and a method for removing a radionuclide or a heavy metal from a target object using the adsorbent. The preparation method of a biomass-based adsorbent for removing a radionuclide or a heavy metal comprises the steps of: a) washing biomass with water and drying the same so as to carbonize the biomass; and b) reforming the carbide obtained in step (a) through an alkali oxidation method. 본 발명은 a) 바이오매스를 수세하고, 건조하여 탄화하는 단계; 및 b) 상기 탄화물을 알칼리 산화법을 통해 개질하는 단계를 포함하는 방사성 핵종 또는 중금속 제거를 위한 바이오매스 기반 흡착제 제조방법 및 그 제조방법에 의하여 제조된 바이오매스 기반 흡착제 및 그 흡착제를 이용한 해당 대상에서 방사성 핵종 또는 중금속을 제거하는 방법에 관한 것이다.
