    Peculiarities of the Adsorption of Heavy-Metal Ions from Aqueous Media by Modified Cellulose by Tatiana E. Nikiforova, Vladimir A. Kozlov, Vera A. Loginova

    Published 2014-05-01
    “…It is established that a-hydroxycarboxyl groups, which are present in all three kinds of sorbents, form colourless chelate complexes due to the replacement of their protons with an equivalent amount of metal ions. Because of the charge transfer during metal–ligand interactions, coloured chelate complexes are formed. …”
