Zusammenfassung:	PURPOSE:To detect the leakage of ammoniacal liquor into cooling water, by using a detector for cyanogen in water in which a silver ion electrode is used as a detecting electrode, and utilizing the fact that an abnormality high potential is indicated when a potential is measured in a water to be detected wherein hydrogen cyanide and hydrogen sulfide are commonly contained. CONSTITUTION:When a cooling pipe 14 in an ammoniacal liquor cooler 13 is broken by the causes such as corrosion and the ammoniacal liquor leaks into the cooling water, the ammoniacal liquor passes through a cooling water pipe 5 and flows into a COG cooler 1. Since hydrogen cyanide and hydrogen sulfide are included in the ammoniacal liquor, a detector 19 for cyanogen in water, which is provided in the COG cooler 1, detects HS, detects the change in potential, and performs meter indication. Based on the signal from the detector 19, a warning indicator is operated, the buzzer of a warning unit is sounded, and a warning lamp is lighted.
