Fe(II)/Chlorine‐Driven Advanced Oxidation of Textile Dyes in a Tubular Microreactor: Continuous‐Flow Performance and Matrix Effects

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT The Fe(II)/chlorine system has emerged as a promising advanced oxidation technology for water treatment, yet its application in continuous‐flow systems remains unexplored. This study presents the first comprehensive investigation of the Fe(II)/chlorine process in a tubular microreactor, a setup that significantly enhances mass transfer and ...

Propolis‐Based Hybrid Nanoflowers as Multifunctional Nanozymes: Structural Integration of Polyphenols for Enhanced Catalytic and Antioxidant Activity

open access: yesChemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT Propolis is a polyphenol‐rich natural resin with well‐documented antioxidant activity; however, its practical application is restricted by poor aqueous solubility and limited stability. Herein, propolis‐based organic–inorganic hybrid nanoflowers (Prp‐Nfs) were synthesized by integrating a propolis extract into a Cu3(PO4)2·3H2O matrix under ...

Sources of dissolved organic matter in initial rainwater and its photochemical activity

open access: yesWater Cycle
The dissolved organic matter in initial rainwater (RDOM), including soil-dissolved organic matter (SDOM) and water-soluble organic matter (WSOM) in the atmosphere, can potentially mediate the migration and transformation of contaminants in natural water.
