On the content of iodine in the water of Izhevsk mineral spring
We investigated minimal amounts of iodine using the microcolorimetric method proposed by M. T. Lecco (in 1896) and developed in detail by Th. v. Fellenberg (in 1923). Basically, this method consists in binding all J, irrespective of its state (free J, iodide, iodate, organic iodine compound), with carbonic alkali and converting it into iodide (KJ), which, when acted on with sulfuric acid, releases free iodine, which stains chloroform red-violet color.
