Description

technical field [0001] The invention relates to the technical field of permanganate index analysis, in particular to a fully automatic permanganate index analysis system. 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 common indicator of the pollution degree of surface water bodies by organic pollutants and reducing inorganic substances. [0003] When the permanganate index analyzer in the prior art performs index analysis on permanganate, the sample is manually added to the sample bottle through a graduated cylinder or a pipette, and the addition of the graduated cylinder will h...
