Preconcentration of Trace Amounts of Pb(II) Ions without Any Chelating Agent by Using Magnetic Iron Oxide Nanoparticles prior to ETAAS Determination
This work investigates the potential of magnetic Fe(3)O(4) nanoparticles as an adsorbent for separation and preconcentration of trace amounts of lead from water samples prior to electrothermal atomic absorption spectrometry (ETAAS) determination. No chemical modifier is required in graphite furnace. Pb(II) ion was adsorbed on magnetic Fe(3)O(4) nanoparticles in the pH range of 5.5-6.5, and then...
متن کاملPreconcentration and Determination of Trace Amounts of Metal Ions in Cast Iron, Granite and Water Using Polyurethane Foam Fun
Polyurethane foam functionalized with β-naphthol was prepared by covalently linking the reagent with the polyurethane foam matrix through –N=N– groups. The reagent-bonded polyurethane foam (β-Nap-PUF) was characterized by use of elemental analysis, UV–visible and IR spectroscopy, thermal analysis (TGA), density, and stability. β-Nap-PUF was found to be very suitable for preconcentration and det...
متن کاملAdsorption and Desorption Process of Chromium Ions Using Magnetic Iron Oxide Nanoparticles and Its Relevant Mechanism
In this study adsorption of Cr(VI) from aqueous solution by Fe3O4 nanoparticles was investigated. Desorption process and recovery of nanoparticles using different solutions were then carried out, and it was observed that NaOH (0.5M) can remove 90% of adsorbed chromium ions. Following the completion of adsorption/ desorption cycles, it was determined that nanoparticles have still had a high abil...
متن کاملApplication of graphene oxide- magnetic nanoparticle for solid phase extraction of trace amounts of cadmium ions in environmental samples
Abstract In this work, Fe3O4-graphene oxide nanocomposite (GO-Fe3O4) was prepared as effective absorbent for magnetic solid phase extraction (MSPE) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (Alizarin red S) and flame atomic absorption spectrometry (FAAS). The GO-Fe3O4 was characterized by scanni...
متن کاملDetermination of Trace Amounts of Nickel by Differential Pulse Adsorptive Cathodic Stripping Voltammetry Using Calconcarboxylic Acid as a Chelating Agent
A method for the determination of nickel(II) by stripping voltammetry is described. The method is based on the adsorptive accumulation of nickel(II) calconcarboxylic acid complex onto a hanging mercury drop electrode (HMDE), followed by the reduction of the adsorbed complex using differential pulse voltammetry. The optimum operating conditions and parameters were found to be 0.05 M NH3/NH4Cl bu...
