Influence of some Impurities, notably Potassium, upon the Reactivity of Iodine Pentoxide towards Carbon Monoxide

CONSIDERABLE quantities of highly reactive iodine pentoxide for use in the determination of carbon monoxide have been prepared successfully from iodic acid made by Lamb's chloric acid process 1,2 . Recently, however, batches giving both high and low initial reactivity have shown a considerable...

Description
Summary:CONSIDERABLE quantities of highly reactive iodine pentoxide for use in the determination of carbon monoxide have been prepared successfully from iodic acid made by Lamb's chloric acid process 1,2 . Recently, however, batches giving both high and low initial reactivity have shown a considerable falling off in carbon monoxide recovery, although the low blank determinations suggested good stability. It has been demonstrated that this poor performance is associated with the presence of potassium as an impurity in the iodine pentoxide.
