Title:
DEVICE AND METHOD FOR RECYCLING METALLIC COMPOUND CONTAINING CORROSIVE SOLUTION
Document Type and Number:
Japanese Patent JP3407731
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method for economically recycling a metallic compound containing corrosive solution reducing, environmental pollution.
SOLUTION: As for the change of the corrosive capacity of a corrosive solution, the tree colors (red, green and blue) of the corrosive solution are monitored by a color sensor, and, in the case the corrosive capacity reduces to a fixed critical value or below, an addition solution capable of reoxidizing the corrosive solution is added, by which the corrosive capacity of the corrosive solution is fixedly maintained, and the corrosive solution is semipermanently reutilized in a unit device without rejecting the same.
