| 摘要 |
The present invention is intended to provide a method for producing a liquid metal chelate compound which may be used as it is or diluted in water or the like, in a very simple procedure, in a short time, in a large quantity, and at a low cost, and to provide a metal chelate compound. A metal is ground in a liquid containing an organic acid to form an unoxidized fine metal powder. For example, a metal is ground in a liquid containing the organic acid, or the organic acid is added after the metal is ground in a liquid, or the organic acid is added while grinding the metal in a liquid. The unoxidized fine metal powder is oxidized in the liquid containing an organic acid to generate a metal ion. As a result of this, the unoxidized fine metal powder is chemically bonded to the organic acid in the liquid thereby producing a liquid metal chelate compound. The liquid metal chelate compound is adsorbed by an absorber.
