AMORPHOUS IRON DETECTOR AND WASTE WATER PURIFIER PROVIDED WITH THIS DETECTOR

摘要

PROBLEM TO BE SOLVED: To monitor treatment performance of a condensate polisher or a filter or the like in a plant generating waste water including amorphous iron and transition element complex. SOLUTION: A light source lamp 5 and a shading filter 7 is provided on a detector cell 2. Light of a single wavelength in a wavelength region of 357 nm to 470 nm generated from the shading filter 7 is transmitted into water to be measured, and a photoelectric tube 8 receiving this transmitted light is provided on a bottom end of the detector cell 2 via a light transmitting plate 10.
