Abstract Effluent from wastewater treatment plants is considered an important source of micropollutants (MPs) in aquatic environments. However, monitoring MPs in effluents is often inefficient owing to the variety in their types. Thus, this study der

Real-time detection of label-free submicron-sized plastics using flow-channeled differential interference contrast microscopy

Autor: Jae Hun Kim, Jiyun Han, Subeen Park, Mingizem Gashaw Seid, Byeongho Park, Soo Hyun Lee, Hyung Min Kim, Jaesang Lee, Seok Won Hong

Owing to the surge in plastic waste generated during the COVID-19 pandemic, concern regarding microplastic pollution in aqueous environments is increasing. Since sub-micron plastics can accumulate in the human body, their real-time detection in water

Changes in levels of N-nitrosamine formed from amine-containing compounds during chloramination via photocatalytic pretreatment with immobilized TiO

Autor: Mingizem Gashaw, Seid, Jeehye, Byun, Wooyul, Kim, Kangwoo, Cho, Seok Won, Hong

Publikováno v: Journal of hazardous materials. 424

We investigated the effectiveness of photocatalytic pretreatment (PCP) of precursors in minimizing the formation potentials (FPs) of carcinogenic nitrosamines, including N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), and N-nitrosodietha

Degradation of ranitidine and changes in N-nitrosodimethylamine formation potential by advanced oxidation processes: Role of oxidant speciation and water matrix

Autor: Seok Won Hong, Mingizem Gashaw Seid, Kangwoo Cho, Chang Ha Lee

Publikováno v: Water research. 203

This study investigated the effects of thirteen (photo/electro) chemical oxidation processes on the formation potential (FP) of N-nitrosodimethylamine (NDMA) during the chloramination of ranitidine in reverse osmosis (RO) permeate and brine. The NDMA

Binder-free immobilization of TiO2 photocatalyst on steel mesh via electrospraying and hot-pressing and its application for organic micropollutant removal and disinfection

Autor: Seok Won Hong, Subramaniyan Ramasundaram, Chang Ha Lee, Mingizem Gashaw Seid, Aseom Son, Eun-Ju Kim, Hyung-Eun Kim

Publikováno v: Journal of Hazardous Materials. 360:62-70

An immobilized photocatalyst was prepared by thermally treating TiO2-coated steel mesh (TiO2-IS) in a laboratory hot-press with no binder. TiO2 coating was performed by electrospraying a 1 mg/mL methanol dispersion of Evonik P25 powder. The thermal t

Ionic-Liquid-Derived Nitrogen-Doped Carbon Electrocatalyst for Peroxide Generation and Divalent Iron Regeneration: Its Application for Removal of Aqueous Organic Compounds

Autor: Seok Won Hong, Kangwoo Cho, Jae Woo Choi, Mingizem Gashaw Seid, Young Jin Ko, Heegon Kim, Wook Seong Lee

Publikováno v: ACS Sustainable Chemistry & Engineering. 6:14857-14865

We investigated the activities of the ionic-liquid-derived (by pyrolysis) nitrogen-doped carbon as the electrocatalyst for the two-electron oxygen reduction reaction (ORR) and regeneration of divalent iron in the electro-Fenton process, focusing on t
