Physicochemical Properties of the High-Field MRI-Relevant [Gd(DTTA-Me)(H2O)2]− Complex

Lothar Helm, Loïck Moriggi, Cora Prestinari

To study the physicochemical properties of the DTTA chelating moiety (H4DTTA = diethylenetriaminetetraacetic acid = N,N′-[iminobis(ethane-2,1-diyl)]bis[N-(carboxymethyl)glycine]), used in several compounds proposed as magnetic resonance imaging (MRI) contr ...

Phototransformation of selected pharmaceuticals during UV treatment of drinking water

Urs von Gunten, Silvio Canonica

The kinetics of Ultraviolet C (UV-C)-induced direct phototransformation of four representative pharmaceuticals, i.e., 17 alpha-ethinylestradiol (EE2), diclofenac, sulfa methoxazole, and iopromide, was investigated in dilute solutions of pure water buffered ...

Non-Cytotoxic, Bifunctional EuIII and TbIII Luminescent Macrocyclic Complexes for Luminescence Resonant Energy- Transfer Experiments

Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver

A new macrocyclic ligand,

L^3

, has been synthesised, based on the cyclen framework grafted with three phenacyl light-harvesting groups and a C5-alkyl chain bearing a carboxylic acid function as a potential linker for biological material. Acidity constant ...

Synthesis of poly(methacrylic acid) brushes via surface-initiated atom transfer radical polymerization of sodium methacrylate and their use as substrates for the mineralization of calcium carbonate

Harm-Anton Klok, Stefano Tugulu, Raphaël Barbey

This manuscript describes the synthesis of poly(methacrylic acid) (PMAA) brushes via surface-initiated atom transfer radical polymerization (SI-ATRP) of sodium methacrylate (NaMA) and their use as substrates for the mineralization of calcium carbonate. A C ...

Kinetics of the oxidation of phenols and phenolic endocrine disruptors during water treatment with ferrate (Fe(VI))

Urs von Gunten

The ability of ferrate (Fe(Vl)) to oxidize phenolic endocrine-disrupting chemicals (EDCs) and phenols during water treatment was examined by determining the apparent second-order rate constants (k(app)) for the reaction of Fe(VI) with selected environmenta ...

Longevity of granular iron in groundwater treatment processes: corrosion product development

Tamar Kohn

Permeable reactive barriers employing iron as a reactive surface have received extensive attention. A remaining issue, however, relates to their longevity. As an integral part of a long-term column study conducted to examine the influence of inorganic coso ...

PH-Triggered assembly of organometallic receptors for lithium ions

Kay Severin, Zacharias Immanuel Grote

The reaction of half-sandwich complexes of ruthenium, rhodium, and iridium with amino-substituted 3-hydroxy-2-pyridone ligands in aqueous solution gives monomeric O,O'-chelate complexes. Upon addition of base, the complexes assemble to form trimeric metall ...

Time scales for sorption - Desorption and surface precipitation of uranyl on goethite

Janet Gordon Hering

The sorption of uranium on mineral surfaces can significantly influence the fate and transport of uranium contamination in soils and groundwater. The rates of uranium adsorption and desorption on a synthetic goethite have been evaluated in batch experiment ...

Hypoiodous acid: Kinetics of the buffer-catalyzed disproportionation

Urs von Gunten

The reactivity of hypoiodous acid (HOI) is an important factor for the fate of iodine in oxidative drinking water treatment. The possible reactions of HOI are its disproportionation, its oxidation to iodate (IO3-), or the reaction with natural organic matt ...

Calcite dissolution in two deep eutrophic lakes

Alfred Johny Wüest, Bernhard Wehrli

The calcium cycle, in particular carbonate dissolution, was analyzed in two deep eutrophic lakes, Lago di Lugano (288 m maximum depth) and Sempachersee (87 m) located in Switzerland. A box model approach was used to calculate calcite dissolution in the wat ...
