| 摘要 |
The invention relates to a method and a device for detecting lead-containing glass pieces in a single-layer material flow of objects comprising primarily waste glass, wherein the objects are irradiated with substantially monochromatic UV light (3), and the fluorescent light resulting therefrom is detected. According to the invention, - the object is additionally irradiated with visible or IR light (4), - the transmission light of the visible or IR light (4) is detected after passing through the object, and - an object is defined as containing lead if both the fluorescent light is present in a predetermined intensity range for at least one predetermined wave range that corresponds to the fluorescence of lead-containing glasses and transmission light is present with an intensity greater zero in a predetermined intensity range. |
