| Abstract: | The potassium dichromate method is used to measure COD Cr in the routine monitoring.The determination by this method is precise and reliable,yet its reflux time is longer,as well as water, power and time-consuming.Therefore,when using this method, the solution of sulfuric acid-silver sulfate is replaced by that of sulfuric acid-phosphoric acid to carry out refluxing operation,which shortens the time of reflux remarkably and accelerates the analysis with satisfactory results. |
