Brief introduction
RB-101A printingtypeCODanalyzer, is an upgraded version designed and produced by Ruibin Technology based on the RB-101 modelCODThe analyzer adopts an imported cold light source for fast and accurate measurement, with better performance. The instrument is based on the relevant standard "Rapid Digestion Spectrometric Method(HJ/T 399-2007)》Designed and manufactured with features such as safety, simplicity, speed, accuracy, direct reading of concentration, printing, and microcomputer control technology.
Scope of application:Suitable for chemical oxygen demand in surface water, underground, domestic sewage, and industrial wastewater(COD)The testing.
2、 Detection principle
RB-101A printingtypeCODanalyzerUsing a closed digestion tube for closed digestion, in a strong acidic solution, a specialized oxidant containing a certain amount of potassium dichromate is used, and under the action of a catalyst165℃Thermostatic digestion of water samples to oxidize reducing substances in the water, and determination of their unreduced products at different wavelengthsCr6+And the ones produced by being reducedCr3+The total absorbance or measurement of the reduced productCr3+The absorbance.
