Original Abstract

Lignitic humic acids and their complexes with cupric ions were prepared in form of thin layers on glass plates and plasma chemically treated in air. The thin layers were prepared by several various ways. They were prepared by evaporation of solvent from humic acids solution in DMSO. Other way was drying of humic gel or its cupric complex. These gels were also plasma chemically modified without drying (water was evaporated during plasma-chemical treatment). Obtained layers as well as original humic acids and their complexes were characterized by means of contact angle, acid-base properties, EPR and FT-IR spectroscopy. It was confirmed that plasma-chemical treatment influences properties and structure of humic samples which play important role in their reactivity and immobilization ability.
