| 摘要 |
This invention relates to a bivalent iron compound comprising a bivalent iron salt, an amino acid and a reducing material. It is known that bivalent iron salts exhibit specific effects in wide applications, for example, agricultural applications such as modification of soil quality, fishing applications such as quality preservation of fishes, medical applications such as treatment of diseases and industrial applications such as prevention of metal corrosion and purification of waste water and exhaust gas. However, the conventional bivalent iron salts suffer a problem that they cannot exhibit such effect for extended periods. This invention was successful in chemically stabilizing the bivalent iron salts by adding amino acids and reducing materials so as to sustain the effects inherent in the bivalent iron salts and to enable utilization thereof in industrial applications.
