Abstract

Removal of heavy metal ions from industrial effluents can be carried out by various separation processes. In this work the aims were (i) to manufacture ion exchange particles from lignocellulotic materials formed as a waste in bio-processes, like biodiesel production from rapeseed; (ii) to apply these particles for copper ions removal and (iii) to compare the effectiveness of the process with different separation techniques: adsorption with chelating and complexationultrafiltation method. In our laboratory ion exchange materials based on lignocellulosic substances was planned to prepare and study. Our aims was to convert the macromolecules of starch- and cellulose-containing materials with the intake of different ionic groups according to the guidelines of the ‘green’ chemistry into polyelectrolytes, which have an adsorptive and ion-exchange capacity much higher than that of the original matrix.
