Abstract

Humic substances are abundant in the environment and they can be isolated in preparative
quantities from low rank coal, peat and soil. Traditionally for their isolation treatment with
solutions of Na OH, KOH or metal salts (K₄P₂O₇) has been used. The aim of this article is to
apply intensive extraction technologies for isolation ofhumic acids from peat
Used technologies provide opportunities to obtain peat humic substances with significantly
higher yields and more rapidly than traditional boiling in alkalic solutions. During the
treatment peat fibers are subjected to major destruction.
