김성범 교수의 연구실은 토양 및 지하수 오염 제거를 위한 나노소재 기반 정화 기술과 미생물 이동 거동을 수학적으로 기반으로 한 환경 모델링을 주요 연구 분야로 다룹니다. 특히, 구리, 인산염 등 중금속 및 영양염 제거를 위한 나노복합재료 개발과 그 재활용 가능성을 연구하며, 전기방울 제조 기반 나노섬유 소재를 활용한 수질 정화 기술도 개발하고 있습니다. 실험적 검증과 수치 시뮬레이션을 융합한 다학제적 접근이 특징입니다.

A mathematical model to describe bacterial transport in saturated porous media is presented. Reversible/irreversible attachment and growth/decay terms were incorporated into the transport model. Additionally, the changes of porosity and permeability due to bacterial deposition and/or growth were accounted for in the model. The predictive model was used to fit the column experimental data from the literature, and the fitting result showed a good match with the data. Based on the parameter values
Nanofibrous adsorbents were fabricated by electrospinning with a blend solution of poly(acrylic acid) (PAA) and poly(vinyl alcohol) (PVA) polymers and used for copper (Cu(<sc>ii</sc>)) removal from industrial plating wastewater.
The aim of this study was to apply iron oxide nanoparticle-chitosan (ION-chitosan) composites to phosphate removal from natural water collected from the Seoho Stream in Suwon, Republic of Korea. Laboratory batch experiments showed that phosphate removal by the ION-chitosan composites was not sensitive to pH changes between pH values of 5.0 and 9.0. During six cycles of adsorption-desorption, the composites could be successfully regenerated with 5 mM NaOH solution and reused for phosphate removal
