Synchronous Fluorescence Spectra of Metal-Fulvic Acid Complexes
- S. Cabaniss
- 1 June 1992
Synchronous quenching spectra, the difference between synchronous scans of ligand fluorescence before and after metal addition, have distinct and readily identifiable patterns for divalent transition…
The role of ultraviolet radiation in litter decomposition in arid ecosystems
Size fractionation upon adsorption of fulvic acid on goethite : equilibrium and kinetic studies
A log-normal distribution model for the molecular weight of aquatic fulvic acids
The molecular weight of humic substances influences their proton and metal binding, organic pollutant partitioning, adsorption onto minerals and activated carbon, and behavior during water treatment.…
A comparison of surface water natural organic matter in raw filtered water samples, XAD, and reverse osmosis isolates.
Reverse-phase HPLC method for measuring polarity distributions of natural organic matter.
Parity distributions indicate that NOM is generally hydrophilic in nature, although XAD-8 isolates are more hydrophobic than RO isolates from the same source, and Hydrophilicity, as indicated by recovery from the HPLC column, is correlated to the elemental oxygen/carbon ratio but does not correlate strongly with molecular weight or 13C NMR aromaticity.
Soil organic matter and litter chemistry response to experimental N deposition in northern temperate deciduous forest ecosystems
The effects of atmospheric nitrogen (N) deposition on organic matter decomposition vary with the biochemical characteristics of plant litter. At the ecosystem‐scale, net effects are difficult to…

These QSPRs improve upon previous work by providing a tested and mechanistically reasonable method for log K(M') prediction with uncertainties comparable to or betterthan other QSPR calibrated with groups of diverse ligands.
Models of Metal Binding Structures in Fulvic Acid from the Suwannee River, Georgia
Fulvic acid, isolated from the Suwannee River, Georgia, was assessed for its ability to bind Ca2+, Cd2+, Cu2+, Ni2+, and Zn2+ ions at pH 6 before and after extensive fractionation that was designed…
