Abstract

The reaction of cobalt cations with humic acids produced from Tisul lignite (Kansko-Achinsk Basin) is investigated. The influence of modification by hydrogen peroxide on the functional-group composition of the humic acids and their sorptional properties is considered. The sorptional capacity of the modified and unmodified humic acids is determined. IR Fourier, ESR, and ¹³C NMR (CP MAS) data show that the sorption of cobalt cations by modified and unmodified humic acids occurs by two mechanisms: ion exchange and complex formation.
