Sorption Rules of Chromium(VI) Ions by Wood-Based Polyampholytes

摘要

The sorption laws of chromium(VI) on highly porous wood ionites in dependence on the pH of the medium, the metal ion concentration in the solution, and the duration of the phase contact have been investigated. It was found that the magnitude of the exchange capacity of the sorbents is defined by the ion state of the functional groups of polyamfolytes and chromate ions in the solution.
