The influence of plasma-solution treatment on the properties of hemp fiber lignin

The effect of an atmospheric pressure gas discharge generated inside an electrolyte solution on hemp lignin has been investigated by the methods of IR spectroscopy. It is shown that the gas-discharge activation causes a threefold increase of the lignin solubility with the further chemical treatment. The feasible processes of the interaction of the active particles generated in the electrolyte solution under the discharge action with the lignin macromolecules are considered.
