Abstract
According to the principle of low-temperature external-heat potassium dichromate oxida- tion-photo-colorimetric method, organic carbon （ OC ） of sludge was determined in the municipal sewage plant. The results showed that absorbance of 0.005 ~ 0.04 g dry sludge was in the standard curve; relative standard deviation of the twelve parallel sludges OC results was 0.66% -the precision was well, and fiducially interval range of their population mean was smaller-the accuracy was also well.关键词
