Abstract
The sorption of Mn2+ ions from aqueous solutions of humic acids derived from Tisul’sk lignite is investigated. The influence of treatment of the humic acids by hydrogen peroxide on their sorptional characteristics is considered. The sorptional capacity of modified and unmodified humic acids for the manganese cation is determined. IR, NMR, and ESR spectroscopy shows that the greater sorptional capacity of humic acids after modification by hydrogen peroxide may be attributed to change in their functional composition.
