Importance of heavy metal-organic matter interactions in natural waters
J.H. Reuter,E.M. Perdue +1 more
TL;DR: In this paper, the role of organic ligands in metal complexing in natural waters has received little attention because of uncertainties regarding both the abundance and nature of dissolved organic carbon compounds, and it has been shown that the bulk of the dissolved organic matter in the natural waters consists of highly oxidized and chemically and biologically stable polymeric compounds closely resembling soil humic substances.

Release of weak and strong copper-complexing agents by algae1
TL;DR: In this paper, the copper-complexing properties of organic compounds released by 21 algal species were characterized by means of potentiometric titrations, and the results showed that most eucaryotic species released measurable amounts (10/sup -6/M) of copper complexing agents that could be modeled as weak organic acids with log k/sub CuL/subcuL/ = 0.5.

Assessment of iron chelates efficiency for photo-Fenton at neutral pH.
TL;DR: The better properties of biodegradability in respect of EDTA combined with better efficiency in terms of microcontaminant removal and the smallest TOC contribution indicate that NTA could represent a useful option to perform photo-Fenton processes at neutral pH.
Journal ArticleDOI
Mobilization of transuranic radionuclides from disposal trenches by natural organic matter
TL;DR: In this paper, the authors demonstrate that even in formations characterized by abundant mineral phases known to strongly adsorb actinides, the actinide can be transported essentially conservatively as NOM complexes.

Determination of the equivalence point in potentiometric titrations. Part II
TL;DR: In this article, the potential -volume curve obtained during potentiometric titrations shows only a small potential change at the end-point, and it has been customary to plot a deltaE/deltaV-volume curve and to take the peak of this curve as the equivalent point.

Computer calculation of equilibrium concentrations in mixtures of metal ions and complexing species.
D.D. Perrin,I.G. Sayce +1 more
TL;DR: A method is described for calculating equilibrium concentrations of all species in multi-metal-multi-ligand mixtures from the pH of the solution, the total concentration of each metal and each complexing agent, and the relevant equilibrium constants (pK(a) values and stability constants).
