摘要：
The loss of biologically active material such as acetic acid during the standard dry matter determination can introduce substantial error into anaerobic digester mass balances. This error may be compensated by performing the determination on sample after titration with sulfuric acid or sodium hydroxide. Data for a variety of materials obtained using the combined titration and drying methods were compared with results from the standard method. The loss of volatile material during drying was confirmed and the two titration corrections validated. The sulfuric acid titration is recommended due to its simplicity and the additional alkalinity information obtained. © 1990.
