Our study investigates the removal of EDCs, PhACs, and PCPs of 10 compounds having different physico-chemical properties (e.g., molecular weight, and octanol-water partition coefficient (Kow)) by nanofiltration (NF) membranes. The rejection of micropollutants by NF membranes ranged from 93.9% to 99.9% depending on solute characteristics. A batch adsorption experiments indicated that adsorption is an important mechanism for transport/removal of relatively hydrophobic compounds, and is related to the octanol-water partition coefficient values. The transport phenomenon associated with adsorption may also depend on solution water chemistry such as pH and ionic strength influencing the pKa value of compounds. In addition, it was visually seen that the retention was somewhat higher for the larger compounds based on their molecular weight. These results suggest that the NF membrane retains many organic compounds due to both hydrophobic adsorption and size exclusion mechanisms. 대한상하수도학회 NF막을 이용한 EDCs, PhACs, PCPs 물질의 제거 특성 평가 Removal characteristics of endocrine disrupting compounds (EDCs), pharmaceutically active compounds (PhACs) and personal care products (PCPs) by NF membrane Article 2 상하수도학회지, v.21, no.3, pp.349 - 357 상하수도학회지 21 3 349 357 kci ART001065323 Nanofiltration endocrine disrupting compounds (EDCs) pharmaceutically active compounds (PhACs) personal care products (PCPs) Adsorption Nanofiltration endocrine disrupting compounds (EDCs) pharmaceutically active compounds (PhACs) personal care products (PCPs) Adsorption 나노여과 환경호르몬 의약품 개인관리용품 흡착
