Problems solved by technology
The invention discloses a method for measuring trace quantity of prussiate in water by using dual-wavelength superposition spectrophotometry. Under the condition that chloramine T exists in a weak acid medium, the prussiate and isonicotinic acid-thiobarbituric acid form red-blue dye which has a principle of dual absorption peaks; a novel method for measuring the trace quantity of prussiate in water through experiment, namely the isonicotinic acid-thiobarbituric acid dual-wavelength superposition spectrophotometry is established and provides a simple, convenient and sensitive analyzing method for measuring the trace quantity of prussiate in a water sample; and meanwhile, the application range of thiobarbituric acid is widened.
