Confirmation of Rapid Determination Method for COD Value of Water Quality
In order to shorten the detection time of chemical oxygen demand(COD value),a standard curve was drawn using potassium hydrogen phthalate,and according to Beer's law,the calibration curve was converted into the chemical oxygen demand of the tested water sample.Mix the reaction solution thoroughly by shaking,shaking,and other methods,then conduct testing,and verify the test results using t-test method.Compared with traditional methods,the new method has strong experimental data reliability and significantly reduces detection time,making it a new means of laboratory COD value detection that can replace the national standard method.
