SYNTHESIS OF LIGNIN-BASED INORGANIC/ORGANIC HYBRID MATERIALS FAVORABLE FOR DETOXIFICATION OF ECOSYSTEM COMPONENTS

Abstract

Combination of lignin matrices (including those modified with silicon oligomers or quaternary ammonium compounds) and such inorganic building blocks as copper and manganese cations (Cu2+, Mn2+) made it possible to synthesize novel hybrid organic-inorganic materials. The synthesized hybrid materials were characterized with significantly increased (2-9 times) values of specific surface area in comparison with those for non-modified and Si-modified precursor matrices. The Cu2+-containing hybrid materials differed by enhanced sorption capacity towards proteins and bacteria.
