Zusammenfassung:	The present invention relates to a per-fluorinated compound adsorbent including layered double hydroxides (LDHs) and a method for removing a per-fluorinated compound using the same. The LDHs according to the present invention not only have a higher adsorption efficiency than the conventional absorbent but also effectively remove a per-fluorinated compound regardless of the type of the per-fluorinated compound or the presence of adsorption-disturbing substances. 본 발명은 층상이중수산화물(layered double hydroxides, LDHs)을 포함하는 과불화합물 흡착제 및 이를 이용한 과불화합물 제거 방법에 관한 것이다. 본 발명에 따른 층상이중수산화물은 종래의 흡착제에 비하여 수중의 과불화합물 흡착 효율이 높을 뿐 아니라, 과불화합물의 종류, 흡착 방해 물질의 존재에 상관없이 과불화합물을 효과적으로 제거할 수 있다.
