Impact of Graphene/Nanocellulose on Nanocomposite Membrane for Methylene Blue Dye Removal and Antifouling Performance

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 43, November 15, 2025.
Nanocomposite membrane for methylene blue dye removal. ABSTRACT The development of membrane technologies in improving water purification systems has been extensively studied by many researchers to ensure efficient production of clean water sources. However, fouling of PVDF membrane results in low permeation and dye removal efficiency, causing a major ...

Isotope Techniques in Chemical Wastewater Treatment: Opportunities and Uncertainties

open access: yesAngewandte Chemie, Volume 137, Issue 19, May 5, 2025.
In this review, we would first introduce basic knowledge about isotopic compounds and then scrutinize the physical and chemical influence induced by isotope changes. Special attention will be paid to the uncertainties in explaining the isotope results.

Effect of remediation of polychlorinated biphenyls (PCBs) contaminated soil by combined treatment of nanoscale zero-valent iron and PCBs-degrading strain

open access: yes浙江大学学报. 农业与生命科学版, 2023
Polychlorinated biphenyls (PCBs) are typical pollutants in soil. Nanoscale zero-valent iron (nZVI) can effectively dechlorinate high-chlorinated PCBs into low-chlorinated PCBs which can be more easily degraded by microorganisms.

A comparative study of removal of methyl tertiary-butyl ether (MTBE) from aquatic environments through advanced oxidation methods of H2O2/nZVI, H2O2/nZVI/ultrasound, and H2O2/nZVI/UV

open access: yesDesalination and Water Treatment, 2016
AbstractThis study compares the efficiency of oxidation with H2O2 and nanoscale zero-valent iron (nZVI)in the presence of ultrasound and that of oxidation with ultraviolet radiation and H2O2/nZVI in the removal of MTBE from aqueous solutions. The effects of some parameters, such as ultrasound, contact time (2–60 min), concentration of hydrogen peroxide

A comprehensive review on the sources, environmental behavior, and degradation of alkylphenol ethoxylates and their metabolites in surface water and soils

open access: yesJournal of Environmental Quality, Volume 54, Issue 6, Page 1631-1652, November/December 2025.
Abstract Alkylphenol ethoxylates (APEOs) and their metabolites, widely used in agricultural, industrial, and household products, are known endocrine disruptors. Since the 1980s, many countries have implemented restrictions on their production and use, necessitating an evaluation of these regulations by reviewing their source and environmental behavior ...
