Abstract
The invention pertains to a process for the regeneration and recovery of periodate from a spent iodate solution, by reacting the iodate with at least an equimolar amount of peroxosulfate. The regenerated periodate is especially suitable for oxidizing carbohydrates to dialdehyde carbohydrates. The oxidation and regeneration can also be carried out in a single stage using a catalytic amount of periodate only.
