Various researchers (Article Degradation of Phenolic Compounds in Palm Oil Mill Effluent ...
) have identify total phenolic content of the wastewater by using F-C reagent method. However, they did not mention the formula for calculting the total phenols from the concentration of Gallic acid obtained from the standard calibration curve. The other issue is, these researchers carried out extraction for identification of TPC. Is there any method (formula) to calculate TPC without extraction.Article Dephenolization and decolorization of olive mill wastewater ...
These authors have identified TPC without extraction but they did not provide the formula for calculating TPC.
