Ethylenediamine Functionalized Nanoporous Silica Type LUS-1 for Highly Sensitive Analysis of Pb2+ , Cd2+ and Zn2+ in Various Samples
In this work, a novel method is described for the preconcentration of Pb2+, Cd2+ and Zn2+ ions in environmental samples using uniform silanized mesopor (LUS-1) functionalized by ethylenediamine groups as a new extractant. The determination of ions is done by inductively coupled plasma optical emissi...

In this work, a novel method is described for the preconcentration of Pb2+, Cd2+ and Zn2+ ions in environmental samples using uniform silanized mesopor (LUS-1) functionalized by ethylenediamine groups as a new extractant. The determination of ions is done by inductively coupled plasma optical emission spectrometry (ICP-OES). The extraction time and efficiency, pH and amount of adsorbent, minimum amount of stripping acid and break-through volume were investigated. The method’s enrichment factor is100 and detection limit is 0.45, 0.05 and 0.03 ng mL-1 for Pb2+, Cd2+ and Zn2+ respectively. The maximum capacity of the one mg of functionalized LUS-1was found to be 150.0 (±2.0) µg and 93.0 (±1.7) µg and 125.0 (±1.2) µg of Pb2+, Cd2+ and Zn2+ respectively.
