Abstract

Abstract : In this study, a simple, rapid and inexpensive approach for the screening of heavy metals with photometric reagents was developed based on porous, anodic aluminium oxide (AAO) films, with detection limits of 0.45 mg L −1 (Co 2+ ), 0.25 mg L −1 (Pb 2+ ) and 0.59 mg L −1 (Ni 2+ ). Abstract : In this study, a simple, rapid and inexpensive approach for the screening of heavy metals with photometric reagents was developed based on porous, anodic aluminium oxide (AAO) films, with detection limits of 0.45 mg L −1 (Co 2+ ), 0.25 mg L −1 (Pb 2+ ) and 0.59 mg L −1 (Ni 2+ ). Noble metal ions Ag + and Pd 2+, as well as Cu 2+, formed nanoparticles within the AAO channels during micro-solid phase extraction driven by galvanic electroless displacement followed by UV detection.
