“…2). As expected, the spectrum shows only the presence of a narrow peak at 1332 cm À 1 due to the first order scattering on the diamond (sp 3 ) crystal lattice. The BDD electrodes were pre-treated by ultrasonication in 2-propanol for about 10 min followed by rinsing with high-purity water to eliminate any organic impurities that may have remained within the BDD film after deposition in the MPCVD chamber.…”

“…The working geometric area was 0.126 cm 2 . The electrochemical oxidation of I 2 , KI and KIO 3 was performed in 1 M NaClO 4 . Sodium perchlorate was used as a support electrolyte because it is electrochemically inert and because the pH value of 1 M NaClO 4 is around 8 and is therefore reasonably representative of real samples such as environmental waters, for which the present technique is developed.…”

“…Deficiency of iodine can lead to mental retardation, endemic goiter and could be a possible cause of stomach cancer [1,2]. In women, such deficiency can lead to overt hypothyroidism and consequent anovulation, infertility, gestational hypertension, spontaneous first-trimester abortion and stillbirth [3]. Moreover, the radioactive isotope 131 I is a fission product of water nuclear reactors, which if released in natural waters, represents a biological hazard for the environment and a serious threat for global health due to its ability to heavily damage cells [4].…”

a b s t r a c tIndividual and simultaneous electrochemical detection of iodide and iodine has been performed via cyclic voltammetry on boron doped diamond (BDD) electrodes in a 1 M NaClO 4 (pH 8) solution, representative of typical environmental water conditions. It is feasible to compute accurate calibration curve for both compounds using cyclic voltammetry measurements by determining the peak current intensities as a function of the concentration. A lower detection limit of about 20 mM was obtained for iodide and 10 mM for iodine. Based on the comparison between the peak current intensities reported during the oxidation of KI, it is probable that iodide (I À ) is first oxidized in a single step to yield iodine (I 2 ). The latter is further oxidized to obtain IO 3 À . This technique, however, did not allow for a reasonably accurate detection of iodate (IO 3 À ) on a BDD electrode.

“…Two sets of fertilizer with different amount of iodine were used. For leaf vegetables, there were five application levels of iodine (12, 25, 50, 100, 150 mg/m 2 ) whereas four application levels of iodine (12,35,70, 150 mg/m 2 ) for fruit vegetables. Compound fertilizer (NPK) was applied twice during growth season.…”

“…The 80% of the iodine in human body and animal original come from edible vegetable food under nature condition [12,13], and the bioavailability of iodine in food can achieve as much as 99%. Due to the fact that iodine in edible plant food originates from soil, the background concentration of iodine in soil as well as its bioavailability determines whether the consumed iodine can meet the need.…”

Iodine biofortification of vegetable plants—An innovative method for iodine supplementation

et al. 2013

To elevate the iodine level in edible plants has been shown to be an excellent approach to correct iodine deficiency. We have proposed an innovative approach to produce iodine supplementation by growing vegetables on soils with algal-based iodized organic fertilizer. Ten species of vegetables were tested. The biological absorption and migration of the iodine within the vegetable plants were revealed using microscopy with silver iodide precipitation technique. The results show that the absorption of iodine by the vegetable increases with increasing amount of the algal-based iodized organic fertilizer in general. And the uptake of iodine by leaf vegetable is significantly greater than that by fruit vegetable. Distribution of iodine in various plant organs shows a trend of decreasing iodine concentration from root, leaf, stalk, to fruit. A similar of decreasing concentration can also be found in various cells (cytoplasm>cytoderm>organelles). The exploration of the iodine uptake and biogeochemistry migration mechanisms provides an important scientific foundation for establishing a new method of producing a natural iodine supplementation by iodine biofortification of vegetables.
