Iodine speciation in basaltic melts at depth [PDF]

Comptes Rendus. Géoscience
The speciation of iodine in basalts has been investigated by combining in situ X-ray diffraction at high pressures and temperatures up to 4.9 GPa and 1600 °C, and Raman spectroscopy on recovered high pressure glasses at ambient conditions.

Iodine speciation in deep eutectic solvents

Physical Chemistry Chemical Physics, 2022
Iodine speciation in deep eutectic solvents is affected by chloride activity, which is controlled by the hydrogen bond donor.

On the Speciation of Iodine in Marine Aerosol [PDF]

Journal of Geophysical Research: Atmospheres, 2022
AbstractWe have compiled and analyzed a comprehensive data set of field observations of iodine speciation in marine aerosol. The soluble iodine content of fine aerosol (PM1) is dominated by soluble organic iodine (SOI; ∼50%) and iodide (∼30%), while the coarse fraction is dominated by iodate (∼50%), with nonnegligible amounts of iodide (∼20%).

Iodine solubility and speciation in glasses [PDF]

Scientific Reports, 2019
AbstractThe study of iodine in glasses and melts is critical in many areas, from geosciences to materials science to waste management. Glasses in the ternary system Na2O-B2O3-SiO2 were studied with the goal of identifying a glass matrix able to dissolve large quantities of this element, and to identify the main parameters affecting the solubility of ...

Iodine speciation in snow during the MOSAiC expedition and its implications for Arctic iodine emissions. [PDF]

Faraday Discuss
Photolysis of iodide in surface snow is a plausible mechanism for supplying reactive volatile iodine to the Arctic atmosphere.

Iodine speciation in a silver-amended cementitious system

Environment International, 2019
Silver-impregnated zeolite (AgIZ) has been used for removing radioiodine from contaminated groundwater and nuclear waste streams and the worldwide inventory of such secondary waste is rapidly increasing. The objective of this study was to 1) quantify the

IODINE SPECIATION IN MARINE AEROSOL [PDF]

, 2015
Iodine chemistry in the marine aerosol plays important roles in the marine boundary layer such as ozone destruction and new aerosol particle formation. Iodine has a complex chemistry in the gas and aerosol phases and to date, what controls iodine speciation, the interactions and roles of individual iodine species are not well understood.

Inorganic iodine speciation in tropical Atlantic aerosol [PDF]

Geophysical Research Letters, 2004
The inorganic speciation of soluble iodine has been determined in size‐fractionated aerosol samples collected from the tropical Atlantic Ocean in October/November 2002 during Meteor cruise 55, a pilot study of the German SOLAS programme. Iodide concentrations were appreciable (>0.4 pmol m−3) in the fine and coarse modes of all samples whereas iodate

Iodine speciation in rain, snow and aerosols [PDF]

Atmospheric Chemistry and Physics, 2008
Iodine oxides, such as iodate, should be the only thermodynamically stable sink species for iodine in the troposphere. However, field observations have increasingly found very little iodate and significant amounts of iodide and soluble organically bound ...

Theoretical evaluation of iodine and selenium speciation in the natural waters of iodine-deficient territories [PDF]

E3S Web of Conferences, 2019
Water migration of iodine, selenium are in many cases directly related to manifestation of thyroid pathologies, in particular, the endemic goiter. The main aim was to evaluate species and conditions of migration of these elements in natural waters from ...
