Production of iodine-enriched food

Abstract: PURPOSE: To obtain an iodine-enriched food useful for modified milk for infants, etc. without using additives other than foods, by feeding an iodine-containing material, e.g. KI, to a dairy cow, milking a milk with a high iodine content, pretreating the milk, drying the pretreated milk and using the resultant powdered milk as a raw material. CONSTITUTION: An iodine-containing material consisting of potassium iodide, calcium iodate, potassium iodate, seaweed and a mixture thereof, etc., is added and mixed with feed for dairy cow and the resultant feed is given thereto. Milking is then carried out to give a milk containing at least 300μg, based on one l milk, iodine, which is then pretreated, e.g. defatted, and dried by the spray-drying method, etc., to afford a powdered milk. The powdered milk is used as a raw material to produce a modified milk for infants, etc., and give the aimed iodine-enriched food. COPYRIGHT: (C)1986,JPO&Japio

Validated green spectrophotometric kinetic method for determination of Clindamycin Hydrochloride in capsules.

Abstract: Simple, sensitive, free of organic solvents, kinetic spectrophotometric method has been developed for the determination of Clindamycin Hydrochloride, both in pure form and Capsules. Method is based on reaction of Clindamycin with potassium iodide and potassium iodate in an aqueous medium at (25 ± 2 °C) to produce yellow-coloured tri iodide ions (I3−). The reaction is followed spectrophotometrically by measuring the absorbance at wavelength 350 nm during 40 min. The effects of analytical parameters on reported kinetic methods were investigated. Under the optimized conditions, the initial rate and fixed time (at 10 min) methods were used for constructing the calibration graphs. The graphs were linear in concentration ranges 1–20 μg ml−1 with limit of detection of 0.12 and 0.22 μg ml−1for the initial rate and fixed time methods, respectively. The results were satisfactory and the analytical performance for both methods was validated. The proposed methods have been applied to determine the components in capsules with an average recovery of 98.25–102.00% and the results are in good agreement with those found by the reference method.

Salt-iodine standard article and its producing method

Abstract: The present invention relates to standard substance for iodine content detection of refined table salt and its preparing process. The standard substance consists of refined table salt, potassium iodate in analytic purity and calcium phosphate in different percentage and is produced into three kinds of products of different, low, mid and high, iodine concentration. The production process includes preparing materials, grinding and sieving, mixing, packing and sealing. The standard substance has simple components, precise content, high homogeneity, high stability, high adaptability and high comparability, and is used in iodine content detection of iodine salt.

Method for making hydrogen and oil by using solar

Abstract: The invention provides a method used for preparing hydrogen and oil by utilizing solar energy, the process flow of which mainly comprises the following procedures: (1) steam is prepared by utilizing the solar energy; (2) salt is prepared and dehydrated; (3) potassium iodate is sintered; (4) oxygen is recovered; (5) potassium iodide solution is hydrolyzed and hydriodic acid is prepared; (6) hydrogen is prepared and iodine is recovered; (7) hydrogen is refined; (8) water is purified; and (9) fuel oil is synthesized and refined by the CO2 conversion and Fischer-Tropsch synthesis process of the H2 prepared in the previous steps and CO2. The hydrolysis of the solutions such as potassium iodide and the like is realized by an electric field decomposer. The device consists of a sealing pipe, two groups of electric field electrodes and a separation plate. The method utilizes the thermal effect and the chemical effect of the sunlight simultaneously, uses the water and CO2 as raw materials to generate hydrogen and fuel oil by chemical reaction, leads the solar energy to be changed into chemical energy which is convenient for use and easy for storage, reduces the cost by at least 30 percent compared with oil produced from coal, provides a new way for solving the energy resource problem, and has huge economic benefits and social benefits.
