Abstract

PURPOSE: To separate nickel iodide and nickel sulfate at a high degree of sepn. by adding metallic nickel to an aqueous mixed acid soln. consisting of hydrogen iodide and sulfuric acid to generate hydrogen and separating the residual nickel iodide and nickel sulfate by making use of a difference in solubility to water.
CONSTITUTION: At an intermediate reaction step of a process of manufacturing hydrogen and oxygen by a thermochemical multistage reaction cycle using iodine, sulfur dioxide and nickel as circulating substances, metallic nickel is added to an aqueous mixed acid soln. consisting of hydrogen iodide and sulfuric acid to generate hydrogen. After finishing the generation of hydrogen, the liq. residue contg. nickel iodide and nickel sulfate is concd. to crystallize the nickel sulfate having lower solubility to water. The crystallized nickel sulfate is then filtered off, and the liq. residue is dehydrated by heating in a gaseous nitrogen stream to obtain anhydrous salt of nickel iodide.
