GPC of soil humic and fulvic acids from Trojmezí area
Šestauberová, Martina ; Novák, František
Humic (HA) and fulvic acids (FA) were isolated from individual soil horizons from podzol of spruce forest in Trojmezí stand (Bohemian Forest, 48°46´25¨ N, 13°51´04¨ E). Their molecular weight M.sub.r./sub. and weight-average molecular weight M.sub.w./sub. were determined by the gel permeation chromatography(GPC). For the high-molecular HA fraction (HM-HA), it was found the range of M.sub.r./sub. 380 – 569 kDa, for the main fraction of HA and for FA 6.7 – 31.4 kDa and 1.8 – 3.3 kDa, respectively. The M.sub.r./sub. of humic substances and the proportion of HM–HA decreased with soil depth. HA isolated from horizon B.sub.h./sub. didn´t contain any high-molecular fraction and its molecular weight approached the values specified for FA.
