Sorption of copper cations by native and modified humic acids

Sorption of copper cations by native and modified humic acids The sorption of copper cations by native and modified humic acids from Tisul’sk lignite (Kansk-Achinsk Basin) is studied on the basis of ESR data. It is found that variation in concentration of the organic paramagnetic centers and in the g factor of humic acids modified by hydrogen peroxide is related to change in their functional composition. The sorption of copper cations from aqueous solutions by native and modified humic acids also reduces the content of organic paramagnetic centers. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

The sorption of copper cations by native and modified humic acids from Tisul’sk lignite (Kansk-Achinsk Basin) is studied on the basis of ESR data. It is found that variation in concentration of the organic paramagnetic centers and in the g factor of humic acids modified by hydrogen peroxide is related to change in their functional composition. The sorption of copper cations from aqueous solutions by native and modified humic acids also reduces the content of organic paramagnetic centers.
