TL;DR: Chloramine-B has been used as an oxidizing agent in hydrochloric acid medium for the indirect volumetric estimations of hydrogen peroxide, lead dioxide, manganese dioxide, selenium dioxide, sodium formate, sodium sulphide, sodium metavanadate, potassium iodate and copper sulphate using iodine monochloride as a catalyst and pre-oxidiser Chloroform is used as indicator It is coloured pink owing to the liberation of iodine during the titration and becomes light pale yellow at the end-point because of the formation

TL;DR: In this paper, a linear regression equation of initial rate and fixed time (absorbance difference) method was evaluated to be Rate (Ʋ) = -1.026 × 10 -6 + 5.93 × 10-4 C and ∆A = - 1.63× 10-3 + 8.0×10-3C.
Abstract: Kinetic method has been developed for the quantitative analysis of streptomycin. The method is based on the oxidation of the drug with the mixture of potassium iodide and potassium iodate to form a yellow colored product. Two methods are adopted for the determination process, the initial rate method and fixed time, absorbance difference method. Both the method followed Beer’s law in the range of 4 µg ml-1- 72 µg ml-1. The linear regression equation of initial rate and fixed time (absorbance difference) method was evaluated to be Rate (Ʋ) = -1.026 × 10 -6 + 5.93 × 10-4 C and ∆A = -1.63×10-3 + 8.0×10-3C. The limit of detection of initial rate method and fixed time method was obtained to be 0.011 and 0.50, respectively while limit of quantitation upon calculation came out to be 0.032 and 1.5 for initial rate and fixed time absorbance difference methods, respectively. Another important study in the proposed method is the activation parameter study which was done at four different temperatures i.e 298 K, 303 K, 308 K and 313 K. Using the elevated temperature various activation parameters such as change in enthalpy (∆ H), change in entropy (∆ S) and Gibbs free energy (∆ G) was calculated and obtained to be -34.41 kJ mol-1, -143.16 and -77.059 × 103 kJ, respectively. Probable mechanism of the reaction has been mentioned in the text.

TL;DR: In this article , the influence of these conditions on iodine contents in vegetables after their fortification and storage (21 °C/230 days) was analyzed, and the results showed that all selected vegetables could be efficient iodine carriers.
Abstract: This study aimed to determine the use of selected vegetables (pumpkin, cauliflower, broccoli, carrot) as carriers of potassium iodide (KI) and potassium iodate (KIO3) by determining changes in iodine content under various conditions of impregnation as the degree of hydration, impregnated sample temperature, and impregnation time. The influence of these conditions on iodine contents in vegetables after their fortification and storage (21 °C/230 days) was analyzed. The results showed that all selected vegetables could be efficient iodine carriers. However, the conditions of the impregnation process are crucial for fortification efficiency, particularly the degree of hydration and the temperature of the impregnated samples before drying. The results showed that the lowest iodine content was in samples fortified at 4 °C and 1:4 hydration. On the other hand, the highest reproducibility of iodine was for the following fortification conditions: temperature of −76 °C and hydration of 1:1. The studies confirmed the higher stability of iodine in KIO3 form compared to KI. To increase recovery of the introduced iodine in the product after drying, using the conditioning step at 4 °C is not recommended. We recommend freezing vegetables immediately after the impregnation process

TL;DR: A simple and inexpensive single solution field kit, specific to iodate, was developed for regular monitoring of salt at consumption level and showed reproducible results for the target range of 0–50 parts per million (ppm) of iodine.
Abstract: Regular monitoring of salt at consumption level is very important for the control of iodine deficiency disorders through iodine fortified salt A simple and inexpensive single solution field kit, specific to iodate, was developed for this purpose The kit showed reproducible results for the target range of 0–50 parts per million (ppm) of iodine The minimum detectable iodine level was 102 ± 0012 ppm (mean ± 2SD, 95 % CI) The shelf-life of the kit was more than 2 years The cost of one kit that monitors 100–150 salt samples was 7 cents (007$) Instructions for preparing the field kit are presented The performance of the kit was evaluated against laboratory iodometric titration About 2,32,000 salt samples in the field and 1,224 samples in the laboratory were tested Excellent agreement was observed between the results of the kit and iodometric titration (R2 = 0999) The intake of adequately iodated salt determined by the kit and iodometric titration was 43 % and 44 % respectively There were no false positive results when bromate or bleaching powder was substituted in place of iodate in salt
