Description
Technical field
The present invention relates to the mensuration field of permanganate index in water, particularly relate to a kind of human resources of reduction and become
The automation equipment of the mensuration permanganate index that basis, mass, automaticity are high.
Background technology
Permanganate index refers under certain condition, with potassium permanganate (KMnO4) as oxidant, processes
The amount of the oxidant consumed during water sample.Representation unit is the mg/litre (O2, mg/l) of oxygen.Permanganate refers to
Number, in conventional Monitoring And Analysis of The Quality, also has the permanganimetric method being referred to as COD.But, by
In this method under prescribed conditions, Organic substance in water can only part oxidized, be not theoretic aerobic
Amount, is not the yardstick of total organic content in reflection water body, therefore, with this term of permanganate index
As an index of water quality, to be different from the COD of potassium dichromate method, more accord with objective reality.
The chemical oxygen consumption (COC) recorded for oxidant with potassium permanganate solution, is formerly referred to as CODMn.
In the environment water quality standard that China is new, this value is renamed as permanganate index, and only by acidity potassium dichromate
The value that method records is referred to as COD.International Organization for Standardization (ISO) suggestion permanganimetric method is only limitted to measure
Surface water, drinking water and sanitary sewage, be not suitable for industrial wastewater.
Different by the medium measuring solution, it is divided into acidic potassium permanganate method and basic potassium permanganate method.Because
Under the conditions of alkalescence, the oxidability of potassium permanganate is more weak than acid condition end, now can not aoxidize chlorine in water from
Son, therefore be usually used in measuring the water sample that chloride ion-containing concentration is higher.
The principle of test is: add potassium permanganate and the sulphuric acid of known quantity in sample, heats 30 in boiling water bath
Minute, some Organic substance in sample and inorganic matter reducing substances are aoxidized by potassium permanganate, add after reaction
The Disodium oxalate. remaining potassium permanganate of reduction of excess, then the Disodium oxalate. by potassium permanganate index solution residual titration excess.
By being calculated permanganate index in sample.
In determining instrument in currently available technology, rely primarily on manual operation, to the requirement of proficiency level very
Height, inefficiency, therefore need badly and a kind of reduce cost of human resources, mass, survey that automaticity is high
Determine the automation equipment of permanganate index.
