| Résumé : |
A test for chemical oxygen demand (COD), requiring approximately 4 hr, is commonly used to monitor the biooxidation of wastes. A test for total organic carbon (TOC), which requires only 3 to 5 min, was compared with the more time-consuming method to determine if it could be used to estimate the COD test and to monitor the biooxidation. Both TOC and COD were determined for various proteins and amino acids, and the results of the two methods correlated well. The biooxidation of tannery unhairing wastes, complex industrial wastes characterized by high solids content, was monitored by both TOC and COD tests. The results obtained indicate that the TOC test is an acceptable alternative to the COD test when the composition of the waste does not vary significantly with time. |
