摘要：
The paper has investigated adsorption of peat fulvic acids from distilled and tap water on activated carbons with different chemistry of the surface when using potentiometric control. It has been shown that water purification of fulvic acids is most expedient on activated carbons having passed “soft” oxidizing treatment. This is enhanced by the charge of the surface lying in the region of the zero charge point, which makes it possible to sorb mainly macromolecular components.
