The prospects for improving the method of adsorption purification in using carbon nanomaterials combined with activated carbons or macroporous adsorption materials as the adsorbent was demonstrated. The results of experimental studies of the adsorption properties of a nanocarbon material - filamentary carbon - in model solutions of ethanolamine containing SF are reported. It was found that in static and dynamic testing conditions, the new material has higher adsorption indexes among activated carbons, including in comparison to the AG-3 and AG-2 carbons widely used in industrial sulfur scrubbers.
