The content of fulvic acids in the primary effluent at the Płaszów WWTP in Kraków

E3S Web of Conferences, 2017
Municipal wastewater contains significant amounts of organic substances of both natural and anthropogenic origin. Wastewater treatment removes most of contaminants, however new substances are formed as a result of biochemical changes taking part during ...

Oxidation of Manganese(II) With Ferrate Revisited: The Overlooked Role of Hardness Cations

AWWA Water Science, Volume 8, Issue 4, July/August 2026.
ABSTRACT Manganese (Mn) is a concern for some groundwater‐sourced drinking water systems. Ferrate (Fe(VI)) is a promising alternative oxidant for Mn treatment, but particle formation during Mn(II) oxidation is not well understood under realistic groundwater conditions with high hardness (> 180 mg/L) and low natural organic matter (< 1 mg/L NOM).

Fulvic Acids and Viral Infections

The Open Conference Proceedings Journal, 2012
Fulvic acids are active principles in humic substances allowing big absorption of mineral ions from soil through vegetables. They are formed by large organic molecules having several reactive sites. Tested in mice and rats with radio- active labeled ions ( 45 Ca 2+ , 32 PO4 3- , 59 Fe 3+ and 131 I - ) in drinking water, it has been found that for even ...

Identification of Sources of Dissolved Organic Matter Using Multi‐Isotope Approach

CLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
• A precise and multi‐isotope method was developed using solid phase extraction (SPE) and Element Analyzer – Isotope Ratio Mass Spectrometry (EA‐IRMS) to characterize the dissolved organic matter (DOM). • The DOM extraction and elution methods were standardized for natural waters containing as low as 0.5 mg DOM. • The extraction efficiencies range from

Propriedades ácido-base e de complexação de ácidos húmico e fúlvico isolados de vermicomposto Acid/base and complexation properties of humic and fulvic acids isolated from vermicompost

Química Nova, 2007
Proton binding properties of humic and fulvic acids were studied by potentiometric titration. Carboxylic groups were the predominant ionizable sites in comparison to phenolic and amine groups.

Humic Acids and EDTA Added to Marine Sediments Improve eDNA Detectability

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Environmental DNA detectability in sediments increased with the addition of humic acid sodium salts prior to lysis. The addition of EDTA before lysis yielded a similar improvement, suggesting that various chelating agents can enhance eDNA recovery and detection. ABSTRACT Sediments are complex and challenging matrices for DNA detections.

Soil Diversity and Climate: An Overview of Profile Data and Acquisition With the WoSIS Global Legacy Dataset

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT Soil profiles are the primary field evidence from which pedogenesis, soil classification and land‐use effects are interpreted, yet their availability remains uneven across climates and land‐cover contexts. Here, we analyse the World Soil Information Service (WoSIS) 2023 snapshot together with Copernicus Global Land Cover 2015 and the global ...

Complexations of Divalent Metallic Ions with Fulvic Acids

Eclética Química, 2018
In this work, the interactions of the functional groups of fulvic acids with copper, cadmium and zinc bivalent ions was investigated by potentiometry. The BEST7 software was employed to investigate the interactions of the functional groups.

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.
