<p>PROBLEM TO BE SOLVED: To provide an iron ion elution device which can enlarge environmental improvement effect with the iron ion widely by performing elution of the iron ion through a movable floating base diffusely.SOLUTION: An iron ion elution device making the iron ion elute under a state that multiple substances including iron are sunk underwater comprises: a floating base 5 which can float and move on a water area 1 such as a lake, a canal, a lake, a river or the sea; a direct vent type outer container 13 provided to the floating base; feed water means feeding water of the water area into the outer container; drainage means which can generate locomotion of the floating base by deriving the water fed into the outer container to the water area; a water passage-type inner container 18 provided in the outer container with several contents and taking the feeding water from the feed water means in with inflow water style and discharging the water to the drainage means; and stirring means 22 stirring the contents in the inner container so that the iron ion can elute. At least either of the water passage-type inner container 18 and the stirring means 22 is rotationally driven.</p> |
