Iodine and bromine speciation in snow and the effect of orographically induced precipitation [PDF]

Atmospheric Chemistry and Physics, 2007
Iodine is an essential trace element for all mammals and may also influence climate through new aerosol formation. Atmospheric bromine cycling is also important due to its well-known ozone depletion capabilities.

A Global Model for Iodine Speciation in the Upper Ocean [PDF]

Global Biogeochemical Cycles, 2020
An ocean iodine cycling model is presented, which predicts upper ocean iodine speciation. The model comprises a three-layer advective and diffusive ocean circulation model of the upper ocean, and an iodine cycling model embedded within this circulation. The two primary reservoirs of iodine are represented, iodide and iodate. Iodate is reduced to iodide

Exploratory Measurements of Singly Substituted and Clumped Isotopologues in Iodate Using Electrospray Ionization Mass Spectrometry. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Clumped isotope geochemistry can reveal the temperatures and chemical pathways at which molecules form, but it remains unexplored for most inorganic systems. Iodate (IO3−) is central to ocean and atmospheric iodine cycling and to tracking radioactive iodine from nuclear activity.

Self-Healing Pd(II) Cage Metallogels for Iodine Capture in Water and Heterogeneous Photocatalysis. [PDF]

Adv Sci (Weinh)
Two carbazole‐derived metal‐organic cages hierarchically self‐assemble into supramolecular metallogels that integrate autonomous self‐healing, reversible stimuli responsiveness, high‐capacity aqueous iodine capture, and visible‐light‐driven photocatalytic sulfide oxidation within a single multifunctional platform.

On the speciation of iodine in aerosol

, 2021
We have compiled and analyzed a comprehensive dataset 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 non-negligible amounts of iodide (~20%).

Iodine speciation and size distribution in ambient aerosols at a coastal new particle formation hotspot in China [PDF]

Atmospheric Chemistry and Physics, 2019
Intense new particle formation (NPF) events were observed in the coastal atmosphere during algae growth and farming season at Xiangshan gulf of the east China coast.

Influence of phytoplankton on iodine speciation in seawater [PDF]

Limnology and Oceanography, 1981
In a study of the influence of cultured phytoplankton on iodine speciation in seawater, no appreciable interconversion of iodide and iodate was observed. The results suggest that phytoplankton, alone, are unlikely to influence iodine speciation in the ocean substantially.

Implications and Practical Applications of the Chemical Speciation of Iodine in the Biological Context

Future Pharmacology, 2022
Iodine is a highly reactive element with a single natural and stable isotopic form (127I). In the biosphere, it is one of the 30 essential elements for life, and its chemical speciation defines its availability and biological activities.

Trypsin Digestion Pretreatment of Kelp Samples and the Iodine Speciation Analysis of Iodate, Iodide, MIT, and DIT by HPLC-ICP-MS

Journal of Chemistry, 2023
The analysis of iodine content in kelp is mainly focused on determining total iodine content, which lacks a rapid and sensitive analytical method for iodine species corresponding to iodate, iodide, monoiodotyrosine (MIT), and diiodo-tyrosine (DIT). Based

Study on the Total Iodine and Iodine Speciation Characteristics in Xilingol League, Inner Mongolia and Tacheng, Xinjiang High Iodine Area by HPLC-ICP-MS

Yankuang ceshi, 2017
Long-term drinking of high-content iodine water will cause harm to human health. The analysis of total iodine and iodine speciation in high iodine groundwater is of great value for iodine environmental geochemistry in high iodine regions.
