Hydrogen Sulfide (H₂S)
Deodorization Test
● About Hydrogen Sulfide
Hydrogen sulfide is heavier than air (specific gravity 1.1905), colorless, highly soluble in water, and mildly acidic. It has a strong, characteristic odor similar to rotten eggs and irritates the eyes, skin, and mucous membranes. It is a toxic gas and is classified as a specific malodor under Japan’s Odor Regulation Law.Although smells from volcanic vents or sulfur springs are often described as “sulfur-like,” sulfur itself is odorless; the smell actually comes from hydrogen sulfide.
● Test Samples
Sample 1: Cotton material soaked in 10% diluted UMO concentrated solution
Sample 2: Cotton material soaked in 5% diluted UMO concentrated solution
Sample 3: Cotton material soaked in 1% diluted UMO concentrated solution
Sample 4: Cotton material soaked in tap water
Notes:
100% cotton running shirts (men’s undershirts, made in Myanmar) were used.
Samples were soaked for 1 hour and then dried.
● Test Method
The samples were placed in a room saturated with hydrogen sulfide gas for 2 hours. After 2 hours, the samples were removed, and the reduction rate (%) of H₂S in the room was measured to evaluate deodorization performance.
● Test Results
The analysis showed that all cotton samples soaked in UMO diluted solution reduced hydrogen sulfide gas.
