TL;DR: In this paper, a solid, storage-stable, germicidal, pre-iodine composition comprises in dry admixture with each other, a solid oxy-compound of iodine, a solvating agent for the oxycompound, and a solid desiccant used in amount sufficient to combine during the storage cycle of the composition with ambient and/or endogenous water.
Abstract: A solid, storage-stable, germicidal, pre-iodine composition comprises in dry admixture with each other, a solid oxy-compound of iodine, a solid reducing agent for the oxy-compound of iodine, and a solid desiccant used in amount sufficient to combine during the storage cycle of the composition with ambient and/or endogenous water. The oxy-compounds of iodine are iodic acid, iodine pentoxide, potassium iodate and sodium iodate. Preferred reducing agents are ascorbic acid, dihydroxy fumaric acid, the thiol sugars and cysteine. A preferred combination desiccant and iodine solvating agent is polyvinyl pyrrolidone having a molecular weight of from 10,000 to 1,000,000. The composition is storage-stable for an indefinite period. Upon the addition of water, the oxy-compound of iodine is reduced to nascent iodine, which, in application, serves its well-known germicidal function.

TL;DR: Potassium iodate in alkaline medium gives a yellowish golden colour having maximum absorbance at 450 nm and provides a basis for the spectrophotometric determination of morphine in the urine of heroin addicts.
Abstract: Morphine in the urine of heroin addicts was identified by TLC using methanol, water, benzene and glacial acetic acid (80:15:15:5) and ethyl acetate, methanol and ammonium hydroxide (25:10:5) as solvent systems and potassium iodoplatinate and iodine as the developing reagents. Potassium iodate in alkaline medium gives a yellowish golden colour having maximum absorbance at 450 nm. By this reaction the minimum limit of identification and quantitative determination of morphine is 2 microg/ml. It provides a basis for the spectrophotometric determination of morphine in the urine of heroin addicts.
