    摘要： An indirect hydrogen sulfide conversion process for the production of elemental hydrogen and sulfur. The process is based upon the electrochemical oxidation of iodide in an aqueous solution with a pH in the range of 0 to 1 at high current densities and current efficiencies. Hydrogen gas is produced concurrently with soluble triiodide. Treatment of a gaseous or non-aqueous liquid stream with electrolyte solutions containing triiodide yields a sulfur product in plastic form. The sulfur product can be recrystallized from a solvent to yield sulfur of comparable purity to that presently produced.

    摘要： Processes are disclosed for the separation of isotopes of an element comprising vaporizing uranyl compounds having the formula (UO.sub.2 A.sub.2).sub.n, where A is a monovalent anion and n is an integer from 2 to 4, the compounds having an isotopically shifted infrared absorption spectrum associated with uranyl ions containing said element which is to be separated, and then irradiating the uranyl compound with infrared radiation which is preferentially absorbed by a molecular vibration of uranyl ions of the compound containing a predetermined isotope of that element so that excited molecules of the compound are provided which are enriched in the molecules of the compound containing that predetermined isotope, thus enabling separation of these excited molecules. The processes disclosed include separation of the excited molecules by irradiating under conditions such that the excited molecules dissociate, and also separating the excited molecules by a discrete separation step. The latter includes irradiating the excited molecules by a second infrared laser in order to convert the excited molecules into a separable product, or also by chemically converting the excited molecules, preferably by reaction with a gaseous reactant.
