摘要： A method of making a cesium salt is described and involves reacting a cesium sulfate containing solution with lime to form 1) a solution containing at least cesium hydroxide and 2) a residue comprising calcium sulfate. The method further involves removing the residue from the solution and converting the cesium hydroxide that is present in the solution to at least one type of cesium salt. The present invention further relates to uses of the cesium salt as well as methods of making cesium hydroxide using lime. Also, methods of making alkali metal salts and alkali metal hydroxides are also described.

摘要： A method for producing an alkali metal iodide salt solution including combusting a liquid for combustion so as to combust a combustible component of the liquid for combustion; and subsequently cooling a resultant gas containing a decomposition product. The method comprises the steps of (a) providing a liquid containing (i) an alkali metal iodide salt, (ii) an inorganic-salt-forming substance capable of forming, at combustion, an inorganic salt containing an alkali metal and (iii) an organic compound; (b) adding to the liquid a precipitation solvent capable of depositing the inorganic-salt-forming substance; (c) removing from the liquid the inorganic-salt-forming substance precipitated in the step (b) so as to obtain the liquid for combustion; and (d) combusting the liquid for combustion and subsequently cooling the resultant gas containing a decomposition product. Accordingly, there can be achieved a method for producing a highly pure alkali metal iodide salt solution from a liquid containing an iodine compound.

摘要： The invention aims at providing a process for the recovery of iodine which can be easily and economically carried out without premixing an iodine compound with an alkali metal compound and a solvent prior to the introduction into a combustion furnace. The aim is attained by a process for the recovery of iodine which is characterized by feeding separately an iodine-containing solution containing iodine and/or an iodine compound and a basic alkali metal compound solution and/or a basic alkaline earth metal compound solution into a roasting furnace to conduct oxidative decomposition of combustibles through heat treatment and fix iodine as stable salts and making the iodine and/or iodine salts contained in the effluent from the heat treatment step absorbed in water or an aqueous solution

摘要： A method for producing halide brine wherein an alkali and a reducing agent are added to an aqueous fluid having a density greater than 8.30 ib/gal., (0.996 Kg/L) water, waste water or sea water for example. The resulting fluid is then contacted with a halogen to form a halide brine. The reaction occurs in a conventional reactor such as a mixing tank.
