Abstract

The invention relates to a modular automatic permanganate index analyzer comprising the following parts of a support frame for positioning and installation of each functional module; a sample cup placement module for placing a sample cup to be tested; a water bath analysis module for performing water bath heating on the sample cup and completing the titration detection of the reagent; an automatedsample removal module for transferring the sample cup between the sample cup placement module and the water bath analysis module; a fully automatic injection module for adding the reagents required for the test into the sample cup in order in fix quantify; and a reagent storage module for storing the reagents required for the test and connected to the fully automatic injection module. The index analyzer provided by the invention adopts a modular design, each module has an independent function, each functional component in the system is low in coupling degree and easy to repair faults, and thedesign of a four-channel injection system is adopted to effectively avoid cross-contamination between different reagents with high test precision.

Description

technical field [0001] The invention relates to the field of water quality analysis, in particular to a modular automatic 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 has the disadvantages of large amount of samples and reagents, time-consuming analysis, ...
