Chemical structure characteristics of lignins and their sorption capacity towards 4,15-diacetoxy-8-(3-methylbutyryloxy)-12,13-epoxytrichothecen-3-ol

Resumo

Chemical structure aspects of the lignins derived from various plants were investigated, and their adsorption capacity towards 4,15-diacetoxy-8-(3-methylbutyryloxy)-12,13-epoxytrichothecen-3-ol (T-2 mycotoxin) was estimated. Specific surface areas and characteristics of capillary-porous structure of the lignins were determined. Correlation ratios between sorption, chemical structure and preparation of the specific surface were estimated. Acidic lignin functional groups play a key role in the adsorption of T-2 mycotoxin.
