초록
수자원의 효과적 활용을 위해 유해물질을 제거하는 기술이 중요하며 흡착이 하나의 경쟁력 있는 기술로 검토/개발되고 있다. 흡착공정이 경쟁력을 가지기 위해서는 뛰어난 성능의 흡착제 개발이 중요하다. 유기물과 무기물 모두를 함유한 금속-유기 골격체(metal-organic frameworks, MOFs)는 큰 표면적, 세공부피, 잘 정의된 세공 구조 및 용이한 기능화등으로 인해 다양한 흡착에 활용되고 있다. 본 고에서는 MOFs를 이용하여 물로부터 유해한 유기물을 흡착제거하는 기술을 요약, 정리하였다. 단순히 흡착량이나 속도를 증가하는 연구 대신에 흡착질과 흡착제 간의 상호작용의 메커니즘을 요약하였고 이를 위해 MOFs를 수정/기능화한 연구를 정리하였다. 이러한 요약으로부터 독자들은 유해물질의 흡착제거를 위한 흡착제의 필요 물성 및 수정에 대해 이해를 하게 될 것이며 흡착 외에 유기물들의 저장 및 전달에 대한 새로운 아이디어를 얻을 수 있을 것으로 기대된다.
Removing hazardous materials from water resources is very important for efficient utilization of the resources, and adsorptive removal is regarded as a competitive technology when good adsorbents with high capacity/selectivity are available. Metal-organic framework (MOF), composed of both organic and inorganic (metallic) species, have been tried for various adsorptions because of huge surface area/pore volume, well-defined pore structure, and facile functionalization. In this review, we summarized technologies on adsorptive removal of hazardous organics from water mainly using MOFs as adsorbents. Instead of reporting high adsorption capacity or rate, we summarized mechanisms of interaction between adsorbates (organics) and adsorbents (MOFs) and methods to modify or functionalize MOFs for effective adsorptions. We expect for readers of this review to understand needed characteristics of adsorbents for the adsorptive removal, functionalization of MOFs for effective adsorption and so on. Moreover, they might have an idea on storage and delivery of organics via understanding of the mechanism of adsorption and interaction.
