The hydrogen peroxide–iodic acid–manganese (ii)–acetone oscillating system: Further observations

Abstract: The redox potential and iodine concentration behavior of the title reaction and component reactions have been examined. The effect of hydrogen peroxide, potassium iodate, manganese (II) sulfate, sulfuric acid, and acetone concentration on the time period and redox potential behavior is reported. Iodine production and consumption rates for the component reactions are given, and some mechanistic suggestions, involving iodine dioxide as the one electron oxidant, are made.

Detection of acid mucopolysaccharides by hematoxylin

Abstract: Author studied the effect of the sequence of the dissolution of components of alumhaematoxylin solution with potassium iodate in it and the effect of the quantity of components on the staining capacity of the dye. Potassium iodate should be added after haematoxylin and alum are dissolved, otherwise the staining of the cartilage and mucus will be less successful. The best staining effect of tissue specimens containing acid mucopolysaccharides and cell nuclei as well can be achieved by the use of haematoxylin solution containing 0,5 per cent of alum. Sections prepared by the freezing technique should be stained by haematoxylin containing 5 per cent of alum.

Calibration checking standard solution for residual chlorine gauge

Abstract: PURPOSE:To facilitate and easy modification as well as to realize a long-time reservation for the calibration checking standard solution of the iodine substitution type polarograph-system chlorine gauge which measures the residual chlorine in the water process system, by using the oxidizing agent which oxidizes the iodine ion and the acid which gives a fixed pH in combination. CONSTITUTION:The calibration checking standard solution for the iodine substitution type polarograph-system residual chlorine gauge is produced by mixing the oxidizing agent which liberates the iodine through oxidization of the iodine ion and the acid (such as the sulfuric acid, nitric acid, etc.) of such amount as to secure pH1.5-3.0 when mixed with the active reagent at introduction into the residual chlorine gauge. The oxidizing agent uses the sodium iodate, potassium iodate, potassium dichromate and the like, and is modified previously up to the 1-1000- fold density compared with the introduction time into the residual chlorine gauge. And in the case of the bromine substitution type polarograph-system liberation chlorine gauge, the potassium salt of bromic acid or the sodium salt is used for the oxidizing agent.

Production of iodineerich cattle milk

Abstract: PURPOSE:To produce high-quality, iodine-rich milk, in high efficiency, whitout damaging the animal, by administering specific iodine compound to reminants. CONSTITUTION:Cattle milk containing >=2ppm of iodine is produced by administering a salt of iodic acid (e.g. calcium iodate, potassium iodate, etc.) to a ruminant such as milch cow. The amount of the iodate is 20-1000mg per 1kg of feed. EFFECT:Iodate is also effective to increase the amount of milk.
