TL;DR: Excessive ingestion of potassium iodate can lead to outer retinal atrophy due to its toxicity to the retinal pigment epithelium and photo-receptors.
Abstract: Iodine deficiency is a common preventable cause of intellectual and developmental disabilities. Iodine in the form of potassium iodate is added to the common salt under the National Iodine Deficiency Disorder Control Program in India. Overdose of iodate can lead to retinal toxicity. We hereby present a case of a 34 year old male patient who presented to us 10 years following iodate ingestion. There was widespread outer retinal atrophy, foveal atrophy and sub-retinal fibrosis noted on fundus evaluation. The fundus fluorescein angiogram was suggestive of window defects while the scotopic electroretinogram showed diminished amplitude pointing towards a grave prognosis. Excessive ingestion of potassium iodate can lead to outer retinal atrophy due to its toxicity to the retinal pigment epithelium and photo-receptors. The degree of damage is dependent on the ingested dose.

20 Nov 2018TL;DR: The method can be used to assess the uncertainty for determination of iodine in urine by As3+-Ce4+ catalytic spectrophotometry, and the major influence factors had a great influence on the extended uncertainty.
Abstract: Objective
To set up an uncertainty assessment method for urinary iodine measurement by As3+-Ce4+ catalytic spectrophotometry, in order to assess the accuracy of this method and find out the major influence factors.
Methods
A mathematical model was established based on the determination method to evaluate the uncertainty component of various factors such as potassium iodate benchmark, standard curve calibration, glass equipment, balance weighing, temperature control instrument, etc., and the uncertainty of the test results of urinary iodine standard substances was analyzed.
Results
The iodine content of the urinary iodine standard material GBW09108i was (72.6 ± 3.7) μg/L, and the relative expansion uncertainty was 5.10%, within the tolerance range allowed by the reference material certificate (10.0%). Among them, the calibration of the standard curve, the uncertainty of the volume of the glass equipment and related consumables had a great influence on the extended uncertainty.
Conclusion
The method can be used to assess the uncertainty for determination of iodine in urine by As3+-Ce4+ catalytic spectrophotometry.

TL;DR: The considerable response of the BR system to adrenaline may be related to the reactions between adrenaline (or its oxidation products) and non-common derivatives of malonic acid or manganese intermediate species.
Abstract: The influence of adrenaline on two iodate based oscillating chemical reactions, the Bray–Liebhafsky (BL) and Briggs–Rauscher (BR) reactions was investigated. It was observed that the addition of adrenaline has different effects on the examined systems. Its addition to the BR system significantly changes the dynamics, while in the BL system, the presence of adrenaline does not show any effect. In order to find out the cause of such a different response of two similar oscillators, UV/VIS spectroscopy was used. Results obtained from recorded UV/VIS spectra indicated that, from all investigated stable reaction species, adrenaline interacts only with potassium iodate and iodine, which are present in both oscillating reactions. Because of this, the different response of the oscillators cannot be ascribed to the reactions between adrenaline and common iodine (stable and unstable) components. As a result, the considerable response of the BR system to adrenaline may be related to the reactions between adrenaline (or its oxidation products) and non-common derivatives of malonic acid or manganese intermediate species.

TL;DR: In this paper, a method of preparing high-purity potassium iodate from crude iodine was proposed, which can reach more than 89% in yield and more than 99.5% in purity.
Abstract: The invention discloses a method of preparing high-purity potassium iodate. An iodine-potassium iodate solution is prepared from crude iodine, thus solving the problem that iodine content cannot be accurately metered when crude iodine is directly fed; by means of the feeding mode of the iodine through dissolution, the problems that during addition of solid iodine, a manhole in a device needs to open for feeding the raw materials, which may cause environment pollution and health damage due to chlorine leakage and iodine volatilization, thereby improving the technical safety. The preparation method is simple and safe, is easy to carry out and low in cost and can reach more than 89% in yield and more than 99.5% in purity. The reaction process is free of generation of high-toxic gas, chlorine,and is free of generation of waste solid, waste gas and waste water. The process is safe and environment-friendly, is low in requirement on equipment, is low in cost, and is easy to achieve in industrial production.
