Description

TECHNICAL FIELD

[0001] The utility model belongs to the related technical field of water manganese content analyzer, concretely relates to a drinking water manganese content analyzer. BACKGROUND

[0002] According to the provision of the sanitary standard for drinking water (GB5749-2022) of our country, the manganese content in drinking water should not exceed 0.1mg / L.When the mass concentration of manganese exceeds 0.1mg / L, the drinking water will emit unpleasant smell, and the utensils and clothes will discolor. The pollution source of manganese in the drinking water is mainly that the mining, industrial wastewater and waste residue flow into the surface water, the net cage fish in the water source and the endogenous pollution make the manganese content exceed the standard seasonally, and the manganese pollution of groundwater is related to the surrounding environment. The color and taste of the drinking water become worse due to the manganese exceeding the standard, and the oxide of manganese is easy to deposit on the inner wall of the pipeline and cause the 'black water' phenomenon. Therefore, detecting the manganese in the drinking water is a necessary measure to ensure that the water quality meets the national standard, and in Japan and Germany, the manganese content is also one of the necessary indexes in water quality monitoring. This shows that the manganese detection has wide importance and application value in the international community.

[0003] However, the existing trace analysis of drinking water manganese generally adopts ammonium persulfate spectrophotometry, the principle of which is that under the condition of the existence of silver nitrate, manganese is oxidized into purple red permanganate by ammonium persulfate, the depth of the color is proportional to the content of manganese, and the content of manganese is calculated by detecting the color depth. The application of this method requires skilled manual operation, and the reagents participating in the reaction contain heavy metal ions such as silver and mercury, which pollute the environment.
