Description

technical field

[0001] The invention relates to a mechanical grasping and moving device for a permanganate index analyzer, in particular to a fast and high-precision automatic sample transfer device for a permanganate index analyzer. Background technique

[0002] The permanganate index refers to the amount consumed when treating water samples with potassium permanganate as the oxidant in acidic or alkaline medium, expressed in mg / L of oxygen. Nitrite, ferrous salt, sulfide and other reducing inorganic substances in water and organic substances that can be oxidized under these conditions can consume potassium permanganate. Therefore, the permanganate index is often used as a comprehensive indicator of the degree of surface water pollution by organic pollutants and reducing inorganic substances.

[0003] At present, the determination of permanganate index mainly adopts the water bath heating oxalic acid titration method of the national standard GB11892-1989. This method requi...
