METHOD FOR PHOTOMETRIC DETERMINATION OF OSMIUM (IV)

摘要

Method for photometric determination of osmium (IV) by which one prepares solution of color-less compound of osmium (IV) with spectro-photometric reagent, with bringing pH with dissolved solutions of chloride acid and sodium hydroxide, with hearting on boiling water bath, cooling and measuring light absorption. The method is in fact that solution of compound of osmium (IV) is obtained at mixing solution of sodium tetraborate, solution of NaCl with reagent, with heating and measurement of light absorption. As reagent one uses alcohol solution of morin.
