Abstract
- The complexation agents 2[-bis-(pyridylmethyl)aminomethyl]-4-methyl-6-formyl-phenol (BPMAMFF) and 2-[2-(hydroxybenzyl)-2-(pyridylmethyl)aminomethyl]-4-methyl-6-formyl-phenol (HBPAMFF) were immobilized on chitosan biopolymer in order to obtain new adsorbent materials for metal ions. The chitosan derivatives were characterized by IR spectroscopy, DSC, TGA, and CHN analysis. The characterization study proved that the chitosan surface was chemically modified with both complexing agents and however, it is expected that these modifications improve the selectivity for metal ions specific in relation to the chitosan.
