The presence of toxic and corrosive hydrogen sulfide in the sulfur hot springs has posed a great concern to sanitary officials, although the physiological effectiveness of these waters has being recognized. We irradiated aqueous sulfur solutions (containing hydrogen sulfide, hydrogen sulfide ions, or thiosulfate ions) and artificial sulfur hot spring water with UV-A (365nm) in the presence of Pt/TiO_2 as photocatalyst. All solutions, except that containing hydrogen sulfide, generated hydrogen in concentrations well above 50ppb (=μg / L). This level has shown to be effective in improving the skin elasticity after habitual bathing. These results suggested that hydrogen-sulfur hot spring using by UV-A could be produced in alkaline sulfur hot springs.
