HYDROGEN-DISSOLVED AQUEOUS SOLUTION AND METHOD FOR PROLONGING THE LIFE DURATION OF HYDROGEN DISSOLVED IN THE AQUEOUS SOLUTION

摘要

The object is to provide an aqueous solution in which hydrogen dissolved therein has a long life duration at low cost. Specifically disclosed is an aqueous solution having hydrogen dissolved therein at a concentration of not less than 0.01 ppm and not higher than the saturated concentration, wherein the aqueous solution contains a substance having a reducing aldehyde group and/or a glycoside hydroxyl group in an amount of 10 to 300000 ppm.
