Chemical Behavior of Iodine in Aqueous Solutions Up to 150C. I. An Experimental Study of Nonredox Conditions.

摘要

The chemical behavior of iodine, I2, in (pH = 6 to 10) aqueous solutions containing 2500 ppm boron as H3BO3 (0.231 M) was studied at temperatures up to 150C. Absorption spectrophotometry was used to identify and monitor the iodine species present. Three objectives were considered: (1) species identification, with special attention given to 'HOI'; (2) the kinetics of reaction between iodine and water to produce iodide and iodate ions; and (3) partition coefficients between liquid and vapor phases for individual iodine species.
