研究室紹介

Professor Jong Kwon Choe's research lab specializes in environmental and materials science, focusing on the fate and behavior of emerging contaminants such as perfluorochemicals (PFCs) in water treatment systems, and the development of advanced oxidation processes for safe water purification. The lab also investigates the impact of microbial activity on subsurface flow in fractured rocks, and explores low-radioactivity materials for use in cutting-edge rare-event detection experiments. Additionally, the lab contributes to food safety technology through innovations in continuous sterilization processes for processed foods.

Perfluorochemicals in Korean Wastewater Treatment Plants: Implications on Sources and Monitoring
주권호, 김용환, 김근영, 송진영, 이미란, 최정권, 최용주

The occurrence of perfluorochemicals (PFCs) in two wastewater treatment plants (WWTPs) in Korea, Plant I and G2, is investigated from a year-round sampling campaign. Plant I influent is characterized by the dominance of perfluorohexanesulfonate showing 10.8-fold higher per capita mass discharge value in the service area than that of Plant G2 service area. Plant G2 influent shows the dominance of perfluorooctanote and perfluorohexanoate, whose per capita mass discharge values are 3.7- and 11.8-fo

Monte Carlo Simulation on the Effect of Fracture Characteristics on Reduction of Permeability by In-Situ Bacteria Growth
C. Han, J.M. Kang, J. Choe
Proceedings of SPE Asia Pacific Improved Oil Recovery Conference

We have simulated the effects of fracture characteristics on the reduction of effective permeability of fractured rocks due to in-situ bacteria growth. A solute is injected continuously to provide food for the growth of in-situ bacteria. We used a power law for fracture length distribution and a fBm for fracture aperture spatial distribution. The results show that in-situ bacteria growth reduces the permeability hyperbolically, but the porosity of backbone fracture does not change significantly.

Formation dynamics of inorganic iodine species during UV-based advanced oxidation of iopamidol and iohexol and their correlation with iodinated disinfection by-product yields
Hongxiu Ji, J.F. Park, Seonyoung An, Seo-Yeong Choi, Jong Kwon Choe
SJR Q1Environmental Science Water Research & Technology

This study compared iodine species formation during treatment of iohexol and iopamidol across different UV-AOPs. UV with NaOCl and PMS fully oxidized iodide to iodate minimizing iodinated disinfection by-products while others did not.

Fluid/Particulate Heat Transfer Coefficient in a Continuous Flow Cooking System

SJR Q2Journal of Biosystems EngineeringOA

우리가 소비하는 가공 식품은 위생상 안전하도록 살균처리가 이루어진다. 식품 내에 존재할 수 있는 유해 세균은 일정 살균온도에서 살균에 필요한 시간 동안 노출되면 사멸하며, 일반적으로 살균온도가 높을수록 살균에 필요한 시간은 단축된다. 연속살균장치는 혼합 및 저장탱크에 담겨진 식품을 점프로 이동시키면서 가열 열교환기에서 살균온도로 가열하고 단열관을 거치는 동안 살균온도를 유지시켜 살균을 완료한다. 또한 살균된 식품은 냉각용 열교환기에서 상온으로 냉각되며 이 과정에서 회수되는 열은 저장탱크에서 유입되는 식품의 예열에 사용되어 에너지 효율을 제고하는데 사용되기도 한다. 이와 같이 관을 이동하면서 가열되는 살균장치는 기존의 배치식 살균방법에 비하여 균일하게 가열이 이루어지므로 130C의 고온으로 살균할 수 있어서 살균에 필요한 시간을 수초에서 수십초 정도로 단축시킬 수가 있고 그에 따라 열손상을 크게 줄일 수 있다. 또한, 상온으로 냉각된 식품을 포장함으로써 저렴한 가격의 포장용기를 사용할

Material radioactivity compilations, such as the one presented here, are important enablers of science. They are useful for the selection of radiopure materials used in the design and construction of low-energy rare-event search experiments. They allow researchers developing such experiments to save time on material studies and avoid costly duplication of effort. The data presented here were generated in support of the planned nEXO double-beta decay search. This work contains among the most rest

석탄가스화복합발전 플라이애시를 활용한 경량 캐스터블의 기계적 특성 평가
박남규, 최정권, 문주혁

본 연구는 IGCC 플라이애시(IGCC FA)를 실리카 퓸 대체재로 경량 캐스터블 내화물에 적용 가능성을 평가하였다. 실험 결과, IGCC FA를 9 % 치환한 샘플은 대조군 대비 압축강도가 90 % 증가하였으며, X선 회절 분석을 통해 C3AH6 형성이 억제된것을 확인하였다. IGCC FA는 실리카 퓸 대비 워커빌리티를 더 효과적으로 개선하였고, SEM 분석에서는 IGCC FA의 구형입자가 작업성을 향상시키는 데 기여함을 확인하였다. IGCC FA는 최대 12 % 치환 시에도 내화도(1410 °C)를 유지하였다. IGCC FA는 물리적, 화학적 특성으로 인해 실리카 퓸을 대체할 잠재력이 크며, 내화물 산업에서 친환경적 대안으로 활용가능하다. 향후 상용화를 위한 표준화 연구가 필요하다.
