production method | electrochemical method sodium iodide solution was added into electrolytic cell for electrolytic oxidation to prepare sodium iodate solution, which was concentrated by evaporation, cooling crystallization, centrifugal separation, drying, preparation of sodium iodate sodium chlorate oxidation of iodine and sodium chlorate according to a certain ratio of ingredients and water into the reactor, with nitric acid to adjust the pH value of the solution is 1~2, the solution is heated with stirring to boil, the reaction is complete and the chlorine gas is removed, the solution is cooled to room temperature, sodium hydrogen iodate crystals are precipitated, and the crystals are filtered and dissolved by heating with hot water, the solution was neutralized to pH 10 by addition of caustic soda and then cooled to crystallize, filtered and dried to obtain a final sodium iodate. 6I2 11NaC1O3 3H2O → 6NaH{IO3}2 5NaCl 3Cl2 ↑ NaH(IO3)2 NaOH → 2NaIO3 H2O |
