| Abstract: | Controlling the heating time for removing NO - 2 and inhibiting induced reaction are the main factors affecting the accuracy of determination when using the method of ammonium chloride for the determination of nitrate content in calcium nitrite solution. After getting rid of the influence factors, the recovery can reach 96.60% above. In comparison with methanol method, ammonium chloride method has advantages such as fast, simple and easy operation, meeting the requirement for the determination. |
