Studies on the interaction of olive cake and its hydrophylic extracts with polyvalent metal ions (Cu(II), Eu(III)) in aqueous solutions
(2009)The paper presents and discusses the chemical affinity of two different forms of natural organic matter (e.g. in solid (SOM) and soluble form (DOM)) for Cu2+ and Eu3+ ions. In the this study SOM is represented by olive ...
