A novel manganese dioxide–hydrogen peroxide (MnO2–H2O2) system was developed for effective Arsenic (As) removal. Under the specified conditions of no external mechanical stirring, a trace H2O2 concentration 0.015 wt%, and MnO2 25 mg/L, high removal efficiency (88%) As (100 µg/L) achieved by MnO2–H2O2 within 30 min, which differs from conventional adsorption processes that require stirring arsen...

Isopropyl alcohol (IPA) is the major organic ingredient in wastewater of semiconductor manufacturing industry. The efficiency of traditional wastewater treatment processes using physicalchemical or microorganism decomposition approaches is limited. Wastewater containing organic solvents that are not decomposed deteriorates the quality of water in the environment, while its volatile nature resul...

Studies on kinetics of galaxolide (HHCB) degradation under influence UV, simulated sunlight and some advanced oxidation processes (H2O2, UV/H2O2, Vis/H2O2) were conducted. Galaxolide appeared to be a photolabile compound. The first-order model was assumed for all studied processes. It observed that basic pH favored HHCB degradation. natural matrices (river water artificial sweat) direct photoly...

BACKGROUND This study examines the dual role of Escherichia coli in the course of ulcerative colitis (UC). The intestinal microbiota is considered to play an important role in UC pathogenesis, but how E. coli contributes to inflammation in UC is still unknown. On the one hand, we demonstrated that there was a significant increase in the number of E. coli at the sites of inflammation in patients...
