The term “cyanide” refers to all of the CN groups in cyanide compounds that can be determined as the cyanide ion, CN-. Originating in water primarily from metallurgical and galvanic industrial plants, cyanide is highly toxic to the human nervous system.
The HI97714 uses an adaptation of the Pyridine-Pyrazolone method to measure cyanide concentrations up to 0.200 mg/L (ppm). When the pyridine-based reagent is added to samples containing cyanide, the sample turns a blue hue; the greater the concentration, the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For cyanide determination, a narrow band interference filter at 610 nm allows only orange light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance of the light hitting the silicon photodetector decreases.
