Objective To establish novel optic fiber sensor for detecting cyanide in water on the spot.
Methods The reaction of ninhydrin and cyanide in water can produce a kind of red-brown products which can be detected by this new Optic fiber senser.
Results The detection limition is 0.01 mg/L with a response range of 0.01-0.1 mg/L.
Conclusion It provided a new method for detecting cyaniole on field and the spot to use optical fiber sensor.
