METHOD OF EVALUATING REACTION BETWEEN DISSOLVED HYDROGEN AND DISSOLVED OXYGEN AND METHOD OF EVALUATING ABILITY OF DISSOLVED HYDROGEN TO SCAVENGE ACTIVE OXYGEN IN WATER

摘要

Provided is a novel technical means for practically applying the antioxidative effect of dissolved hydrogen and obtaining a finding which is useful in practically applying a reaction of scavenging active oxygen in water. A reaction between dissolved hydrogen and dissolved oxygen is quantitatively evaluated based on a time-profile of the difference between the dissolved oxygen amount measured in the presence of forcibly dissolved hydrogen and the dissolved oxygen amount measured by blowing a gas other than hydrogen. Further, a reaction between dissolved hydrogen and dissolved oxygen is quantitatively evaluated based on a time-profile of the difference between the dissolved oxygen amount measured in the presence of forcibly dissolved hydrogen in water which contains a photosensitive dye and the dissolved oxygen amount measured in the presence of forcibly dissolved hydrogen in water which contains no photosensitive dye.
