CO2‐Responsive Smart Wood Scaffold for Natural Organic Matter Removal without Secondary Pollution

open access: yesAdvanced Materials, Volume 37, Issue 30, July 29, 2025.
A CO2‐responsive smart wood scaffold is developed for sustainable water purification, achieving efficient natural organic matter (NOM) removal and microbial disinfection without secondary pollution. The CO2‐responsive polymer coating undergoes protonation upon CO2 exposure, enabling strong cation−π interactions with NOM.

Interactions of chlorine with tropical aquatic fulvic acids and formation of intermediates observed by fluorescence spectroscopy

open access: yesJournal of the Brazilian Chemical Society, 2004
The interactions of tropical aquatic fulvic acids (AFA) with chlorine and formation of trihalomethanes were characterized by fluorescence spectroscopy. The aquatic humic substances (AHS) were isolated from a dark-brown stream (located in a environmental ...

Water‐Soluble Iron Porphyrins as Catalysts for Suppressing Chlorinated Disinfection Byproducts in Hypochlorite‐Dependent Water Remediation

open access: yesChemSusChem, Volume 18, Issue 9, May 5, 2025.
Water remediation using chlorine (for which hypochlorite is the active disinfectant) has the disadvantage of degrading micropollutants to chlorinated compounds. To bypass this and promote total mineralization of the model micropollutant phenol to CO2 and H2O, we investigated the use of catalytic amounts of iron porphyrins in hypochlorite‐dependent ...

Fluorescence characteristics of dissolved organic matter (DOM) in bottled drinking water of different countries: A potential risk to public health

open access: yesWater Environment Research, Volume 97, Issue 4, April 2025.
Fluorescence dissolved organic matters (DOM) in bottled drinking water from different countries using fluorescence spectroscopy were characterized. The identified microbial risk because of DOM presence in bottled water can utterly cause severe health problems and economic loss, and raise questions on the efficiency of drinking water treatment ...

Formation of iodo-trihalomethanes, iodo-haloacetic acids, and haloacetaldehydes during chlorination and chloramination of iodine containing waters in laboratory controlled reactions [PDF]

open access: yes, 2017
Iodine containing disinfection byproducts (I-DBPs) and haloacetaldehydes (HALs) are emerging disinfection by-product (DBP) classes of concern. The former due to its increased potential toxicity and the latter because it was found to be the third most ...

Biodiversity and ecosystem service contributions of trees: A review for environmental risk assessments of non‐native plant pests in Sweden

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Plant pests, particularly non‐native species, can have a profound impact on their host plants. Trees are the foundation of forest ecosystems and serve as important structures in agricultural landscapes and urban areas. In Sweden, forests cover around 70 % of Sweden's land area and serve as an important national resource for the economy and for

Development of a simple analytical method for determining trihalomethanes in beer using a headspace solid-phase microextraction technique

open access: yesQuímica Nova, 2013
We developed a simple, rapid, and solventless method for analyzing trihalomethanes in beer samples using headspace solid-phase microextraction. The effects of varying experimental parameters, such as extraction temperature and time, addition of sodium ...
