설명

일반 설명

Ammonium sulfate is an ammonium salt commonly used as fertilizer. It can be synthesized by neutralizing sulfuric acid with ammonia.[1] It can enhance the phytotoxicity of several herbicides like glyphosates.[2] Ammonium sulfate is formed as a co-product during the manufacture of caprolactam, a precursor of nylon.[3]

애플리케이션

Ammonium sulfate was used in methyl cellulose precipitable tannin assay to evaluate wine tannin in finished wine samples.[4] It was also used in making externally mixed aerosols for analyzing the 1 × 3 tandem differential mobility analyzer (1 × 3-TDMA), which is mainly employed for determining the irreversibility of the hygroscopic growth factor of aerosol particles.[5]
