Speciation of iodine in marine aerosol

, 2021
We have compiled a comprehensive dataset of field observations of iodine speciation and size distribution in marine aerosol (1983-2018). Since the source of iodine is mainly marine, only ship-borne campaigns (16 cruises) and coastal or insular campaigns (

Rapid Determination of Inorganic and Organic Iodine in Edible Salt and Kelp Samples by a Z-Ⅱ Iodine Probe

Yankuang ceshi, 2020
BACKGROUND At present, iodine content in edible salt and kelp products is mainly determined as the form of total iodine content, but the speciation analysis of inorganic iodine and organic iodine mainly relies on the hyphenated techniques of large-scale ...

Abatement of radioiodine in aqueous reprocessing off-gas

Frontiers in Chemistry, 2023
The reprocessing used nuclear fuel (UNF) releases volatile fission and activation products, including 129I, into the off-gas of a processing plant. Mitigation of the release of vapor phase radionuclides is necessary for meeting regulatory requirements in

Senescence as the main driver of iodide release from a diverse range of marine phytoplankton [PDF]

Biogeosciences, 2020
The reaction between ozone and iodide at the sea surface is now known to be an important part of atmospheric ozone cycling, causing ozone deposition and the release of ozone-depleting reactive iodine to the atmosphere.

Bromide–Borate Coupling Enables Selective Electrochemical Oxidation of Glycerol to Dihydroxyacetone

Angewandte Chemie, EarlyView.
Bromide–borate coupling enables selective electrochemical upgrading of glycerol to dihydroxyacetone (DHA). Electrogenerated bromine species mediate glycerol oxidation, while borate coordination biases selectivity toward DHA, enabling carbon‐balanced oxidation and high productivity in flow‐cell operation.

Iodine speciation and cycling in fresh waters: a case study from a humic rich headwater lake (Mummelsee)

Journal of Limnology, 2009
Iodine is a vital micronutrient for all mammals, including humans. Despite iodine's listing by the WHO as the world's most easily preventable cause of brain damage, there is very little known about iodine cycling in terrestrial freshwaters, particularly ...

Chlorination‐Driven BODIPY Fluorescent Probes for the Selective Monitoring of Myeloperoxidase Activity in Cells and Inflamed Mouse Models

Angewandte Chemie, EarlyView.
A meso‐carboxamide‐substituted BODIPY fluorescent probe reports myeloperoxidase (MPO) activity via electrophilic chlorination by MPO‐derived HOCl, generating a highly emissive chlorinated product with a ca. 40 nm bathochromic shift. Applications in quantitative MPO assays, cellular imaging of MPO‐derived HOCl, redox‐dependent discrimination of cancer ...

Speciation of ¹²⁷I and ¹²⁹I in atmospheric aerosols at Risø, Denmark: insight into sources of iodine isotopes and their species transformations [PDF]

Atmospheric Chemistry and Physics, 2016
Speciation analysis of iodine in aerosols is a very useful approach for understanding geochemical cycling of iodine in the atmosphere. In this study, overall iodine species, including water-soluble iodine species (iodide, iodate and water-soluble ...

Extension of the AIOMFAC model by iodine and carbonate species: applications for aerosol acidity and cloud droplet activation [PDF]

Atmospheric Chemistry and Physics, 2022
Iodine and carbonate species are important components in marine and dust aerosols, respectively. The non-ideal interactions between these species and other inorganic and organic compounds within aqueous particle phases affect hygroscopicity, acidity, and

A review on speciation of iodine-129 in the environmental and biological samples [PDF]

Analytica Chimica Acta, 2009
As a long-lived beta-emitting radioisotope of iodine, (129)I is produced both naturally and as a result of human nuclear activities. At present time, the main part of (129)I in the environment originates from the human nuclear activity, especially the releases from the spent nuclear fuel reprocessing plants, the (129)I/(127)I ratios have being reached ...
