Document Type and Number:
Japanese Patent JP7294951
Kind Code:
B2
Abstract:
To provide a processing method of water to be treated, containing an iron carbonyl cyano-complex, which has been difficult to process in the conventional method, without mass use of a copper compound, to remove the iron carbonyl cyano-complex from the water to be treated.SOLUTION: In the method, a water to be treated W1 containing an iron carbonyl cyano-complex of one or both of [Fe(CN)(CO)]and [Fe(CN)(CO)]is allowed to contact with an anion-exchange resin 111 in a reaction tank 11, followed by separating the anion-exchange resin 111 adsorbing an iron carbonyl cyano-complex by an ion exchange action in a solid-liquid separation tank 14.SELECTED DRAWING: Figure 1
