Photooxidation of herbicide amitrole in the presence of fulvic acid

Environmental Science and Pollution Research, 2017
Fulvic acid (Henan ChangSheng Corporation) photoinduced degradation of non-UVA-absorbing herbicide amitrole (3-amino-1,2,4-triazole, AMT) as a way for its removal from polluted water was investigated in details. It was shown that the main primary species generated by fulvic acid under UVA radiation, triplet state and hydrated electron, are not directly

Effect of fulvic acid on neodymium uptake by goethite

Journal of Colloid and Interface Science, 2012
Experimental studies of the interaction of aqueous neodymium (Nd), Suwannee River fulvic acid (FA), and solid phase goethite were conducted. Results from blank systems (individual Nd and FA), binary systems (Nd-goethite, FA-goethite, and Nd-FA), and ternary systems (Nd-FA-goethite) at 0.1 mol/kg and 25°C are reported. In the binary Nd-goethite system a

Fluorescence quenching of fulvic acids by fullerene in water

Environmental Pollution, 2013
Fullerene can be suspended in water as nanoscaled-fullerene-aggregates (nC(60)). However, little is known about its biogeochemical cycling in natural waters. In this paper, the interactions between nC(60) and fulvic acids were investigated using fluorescence spectroscopy and fluorescence quenching titration.

Fulvic acid: modifier of metal-ion chemistry

Environmental Science & Technology, 1982
Fulvic acid, which is derived from the decay of plants and animals, is being studied for its role in the transport and toxicity of metal ions in soil and water. It is discussed in relation to the origin of humic substances and its interactions with metal ions. Techniques for investigating complexes of fulvic acid and metal ions are presented.

Europium binding by an aquatic fulvic acid. Interaction functions for the “average” sites in the fulvic acid molecule

Science of The Total Environment, 1991
Abstract The interaction of a well characterized aquatic fulvic acid, Bersbo FA, with Eu 3+ has been studied using ion-exchange distribution studies and an ultrafiltration method. The results indicate that values of overall stability constants, Q MFA , obtained in the ion-exchange distribution studies (log Q MFA = 6.00–8.55), which increased ...
