Monomeric phenols including phenolic acids occur ubiquitously in soil and can be stabilized by soil matrices; however, the stabilization mechanisms are still unclear. Using a dialysis equilibrium system, we quantitatively studied the abiotic association of uniformly ring- 14 C-labelled catechol, p-hydroxybenzaldehyde, protocatechualdehyde, vanillin, p-coumaric acid, ferulic acid, and caffeic...
Organic matter from profundal lake sediments was fractionated and analyzed with high depth resolution, and the size-class distribution of humic substances was determined by gel-permeation chromatography. Together with a depth-dependent increase of the thermal stability of the organic matter and an increasing C/N atomic ratio of the humic acids, the size-distribution patterns of different fractions...
