Abstract
PURPOSE: To measure the quantity of chrome adhering on a surface of metal, such as, zinc, etc. in a non-destructive shape, by chemical-synthetic treating the said metal with a chromic acid system, and the measuring the concentration of metallic ions contained in the treated liquid.
CONSTITUTION: When measuring the quantity of chrome, which adheres, of zinc, aluminum, a zincified steel plate or the like chemical-synthesis treated with a chromic acid system, the concentration of metal dissolving in liquid chemical-synthesis treated is measured, and the quantity of chrome in a film formed on a surface of metal is grasped on the basis of the value.
