Aqueous-Phase Brown Carbon Formation from Aromatic Precursors under Sunlight Conditions

open access: yesAtmosphere, 2020
At present, there are still numerous unresolved questions concerning the mechanisms of light-absorbing organic aerosol (brown carbon, BrC) formation in the atmosphere. Moreover, there is growing evidence that chemical processes in the atmospheric aqueous

Dynamic studies of nitrophenols sorption on perfil in a fixed-bed column

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2008
The adsorption of two substituted nitrophenols, namely 4-nitrophenol (4-NP) and 2,4-dinitrophenol (2,4-DNP), from aqueous solutions onto perfil was studied using a fixed bed column.

Biodegradation of P-Nitrophenol by Engineered Strain [PDF]

open access: yesAMB Express, 2021
Abstract p-Nitrophenol (PNP) is an important environmental pollutant and can causes significant environmental and health risks. Compared with the traditional methods, biodegradation is a useful one to completely remove the harmful pollutants from the environment. Here, an engineered strain was first constructed by introducing PNP biodegradation

Use of redox mediators for the enhanced degradation of selected nitrophenols

open access: yesApplied Water Science, 2019
In the present study, sequential anaerobic–aerobic treatment was used for the enhanced degradation of selected nitrophenols. Five identical reactors were used to assess the degradation of 2-nitrophenol and 2,4-dinitrophenol. Reactor 1 was used as control,

Functionality-based formation of secondary organic aerosol from m-xylene photooxidation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Photooxidation of volatile organic compounds (VOCs) produces condensable oxidized organics (COOs) to yield secondary organic aerosol (SOA), but the fundamental chemical mechanism for gas-to-particle conversion remains uncertain.
