Abstract
The Folin-Ciocalteau reagent was used to determine the total content of soluble peat phenolic compounds by a colorimetric method. The response of known phenolic compounds to the reagent was measured and it indicated its usefulness for studying peat humus. The results showed that the absorbance at 550 nm of the Na4P2O7 extracts of peat materials from two peat soil profiles was correlated with the total phenolic content but anomalous results were encountered in some horizons. Additionally, the total phenolic content per microgram of dissolved organic matter and the behavior of known phenolic compounds revealed that one peat profile had the most reactive phenolics in the bottom horizon.This publication has 2 references indexed in Scilit:
