Comparativestudy on fast oven method and classical reflux method of chemical oxygen demand determination in water
In this paper, the chemical oxygen demand of low concentration standard sample, high concentration standard sample, environment sample of national and provincial control section and import and export water sample of sewage treatment plant were measured and analyzed by fast oven method and classical reflux method respectively. Results showed that the data obtained by the fast oven method had the same accuracy and precision as the classical reflux method. When the number of samples per batch was large, the operating procedure and cost of fast oven method were superior to the classical reflux method.
