Model WDet-5000CN - Cyanide Water Quality Online Analyzer



Under the condition of weak acid, cyanide of water samples and chloramine T generate chloramine cyanide,and then react with isonicotinic acid, after the hydrolysis generate pentene dialdehyde,finally, together with barbituric acid generate purple blue compounds,in a certain concentration range, the chroma is proportional to the concentration of cyanide.
