ABSTRACT
A simple rapid method for the determination of
hydrogen molecule in water is developed. This method is based on the redox
reaction of ferric ion and hydrogen molecule in the presence of colloidal
platinum. The released ferrous ion was developed with o-phenanthroline and spectrophotometrically measured at 510 nm. The
suitable pH condition of redox reaction of ferric ion and hydrogen molecule is
pH 2. And 1 mol of molecular
hydrogen reduced 2 mol
of ferric ion. The molar coefficient for hydrogen molecule is 2.25 × 104 L⋅mol-1⋅cm-1.
The stability of hydrogen water was also discussed.
KEYWORDS
