연구실 소개
이 교수의 연구실은 환경 오염 물질, 특히 영구유해물질(PFAS), 조류 번식, 농도 유기물 등 수질 오염 문제를 해결하기 위한 고기능성 나노소재 및 정수 기술 개발에 주력하고 있습니다. 메탈 유기 프레임워크(MOFs)를 활용한 PFAS 제거 기술, 크로마토그래피 기반 수용성 유기물 분포 분석, 그리고 고도정수처리 기술(예: MF-NF, UV-AOP)을 통한 복합 오염물질 제거에 대한 연구를 진행 중입니다. 특히, 실제 수질 환경에서의 적용 가능성을 고려한 실증적 실험과 사회적 수자원 접근성 문제까지 통합적으로 고려한 연구가 특징입니다.

주요 논문
11Per- and polyfluoroalkyl substances (PFASs) are a category of extremely persistent environmental pollutants. Metal-organic frameworks (MOFs) have appeared as promising adsorbents for PFAS removal due to their large surface area, tunable porosity, and versatile surface chemistry, which are among the numerous treatment technologies available. This review critically evaluates current developments in the design, fabrication, and application of MOF-based (nano)materials for the adsorption of PFAS in
Size exclusion chromatography (SEC) is a useful tool for understanding the apparent molecular weight (AMW) distribution of dissolved organic matter (DOM). However, the limitation that a single analytical column generally cannot resolve the entire AMW range of DOM from hundreds of daltons to hundreds of kilodaltons often oversimplifies the interpretation of the AMW distribution. This study applied the nonnegative matrix factorization to deconvolute SEC chromatograms and cross-validated deconvolut
The seasonal occurrence of algae blooms in surface waters remains a common problem, such as taste and odor (T&Os), the risk of disinfection by-products (DBPs), and disturbance to water treatment systems. The coagulation efficiency of plant-mineral composite (PMC) coagulant followed by UV-based advanced oxidation processes (UV-AOPs; UV/H2O2 and UV/Cl2) was evaluated for removal of algae, turbidity, dissolved organic matters, and taste and odor compounds in lab-scale and pilot-scale tests. In
This study shows that combined microfiltration–nanofiltration (MF–NF) treatment effectively removes contaminants from secondary wastewater effluent derived from a facultative lagoon system.
This study showcases, from a technical and social perspective, the evolution of water pollution in Salvadoran rivers. As a novel contribution on this matter, the study also reveals the presence of emerging contaminants in the Lempa River and the Cerrón Grande Dam as well as in drinking water of a popular town in San Salvador, the Salvadoran capital city. All this information has been used to analyze the hydrosocial cycle and the way in which the lack of access to quality water affects the lives
