| titleOfInvention | Flow injection colorimetric detection method and device for ammoniacal nitrogen |
| abstract | A flow injection colorimetric detection method for ammoniacal nitrogen is disclosed. The NaOH solution that has a concentration range of 0.01-0.03 mol is used as a releasing liquid, and is injected into a capillary system that is connected with a gas-liquid separator. The gas-liquid separator includes a deep groove. A quantified liquid sample is injected into the releasing liquid in the capillary system and forms a sample strip. The sample strip flows in a circle with the releasing liquid pumped into the capillary system, and releases NH3 when flowing by the deep groove of the gas-liquid separator. NH3 diffuses to the groove outlet, and permeates through a breathable film, and changes the color of the acid-alkali indicator in a capillary slot. The sample strip circles continuously till NH3 is fully released. The acceptant liquid that has absorbed NH3 is pumped into a flow cell of a colorimeter by an injecting pump, and is irradiated by the light that has a wavelength of 560 nm. The concentration of the ammoniacal nitrogen in the sample liquid is detected through photoelectric conversion. |
