Sodium iodine is a more expensive substance. As long as there is no deterioration, why must be destroyed, it is better to give it to the laboratory.

To say that destruction, you can dissolve in water in advance, distribute it into a dilute solution, and then add an appropriate amount of NAHSO3 solution at 0 ° C at low temperature.
NAIO4+4NAHSO3 \u003d\u003d\u003d 4NAHSO4+NAI; then add NAHCO3 solution to the reaction solution to adjust the pH to 5-8, so that the NAHSO4 in it can be completely neutralized, which can be discharged (NAIThe harm to water bodies is smaller than NAIO4, after all, there is no oxidation; sodium sulfate is conventional substances, and it will hardly cause harm to water bodies).
