摘要：

The efficiency of recovery of uranium(VI) from aqueous solutions with hydrolytic lignin and strength of binding of uranium to lignin were studied in relation to the uranium concentration and acidity. The mechanisms of sorption of uranium were analyzed by the methods of sequential leaching of uranium from lignin and IR spectroscopy.
