Application of pyridine functionalized MCM-41 nanoporous adsorbent for copper extraction in water samples

In this work, a novel method is described for the preconcentration of Cu2+ ions in environmental samples using uniform mesoporous MCM-41 functionalized with pyridine groups. The determination of ions is done by flame atomic absorption spectroscopy. The extraction time, pH and amount of adsorbent, minimum amount of stripping acid and break- through volume were investigated. The method’s enrichment factor is 30 and detection limit is 0.1 ngmL-1.
