Abstract
The sorption properties of technical-grade lignins were studied with respect to 1,1-dimethylhydrazine. It has been found that the lignin obtained by means of hydrolysis exhibits a high sorption capacity with respect to 1,1-dimethylhydrazine owing to a greater number of active sorption centers. Dynamics has been studied for binding unsymmetrical dimethylhydrazine by the hydrolytic lignin.
