Özet

The present study as simple and efficient is based on application of platinum nanoparticle loaded on activated carbon (Pt-NP-AC) which characterized by SEM, TEM and XRD. Pt-NP-AC and activated carbon (AC) that efficiently modified by impregnation of new chelating agent (bis (4-chlorobenzylidene)-1, 2-ethanediamine (BCBEN) for enrichment of Pb2+, Cu2+, Cd2+, Co2+ and Zn2+ ions. The retained metal ions were efficiently eluted and subsequently was quantified and the laterally the results correspond to Pt-NP-AC and AC was compared. The dependency and relation among recovery of understudy metal ions to variables like pH, amount of ligand and/or solid phase and eluent condition was optimized and it was reveal that Pt-NP-AC and AC, preconcentration factor was 90 for understudy metal ions and detection limit was between 1.5-2.2ng mL(-1). The recovery of studied elements by proposed method was >97% with low relative standard deviation (RSD < 2.4%). (C) 2015 Published by Elsevier B.V.
