We measured the organic matter in two samples by gravimetric method, volumetric method (potassium dichromate method) and the instrument method, found that weight method was a little higher than the other two methods (49.7% and 44.4%; 47.1% and 44.441.0%; 48.5% and 38.1%). The results of Potassium dichromate volumetric method and the instrument method were similar (method of relative deviation between these two samples were 1.5% and 3.7%, re- spectively). Here, we compare the results of organic matter content in the samples by three me- thods, suggesting the correlation between different methods of organic matter in municipal sludge.
