Magnetic Solid ‒ Phase Extraction of Trace Amounts of Nickel in Food Samples Using Polydopamine Coated Fe3O4 Nanoparticles

Mohsen Nekoeinia; Saeed Yousefinejad; Mohammad Reza Abdi; Behnam Ebrahimpour

Volume 4, Issue 2 , September 2017, Pages 1-9

Abstract
  A simple and a green methodology has been developed for the preconcentration of Ni2+ based on the adsorption of its dimethylglyoximate complex on polydopamine coated Fe3O4 nanoparticles. The adsorbed complex was easily desorbed using 1.0 mL of CHCl3 and the concentration of nickel was determined by UV-Vis ...  Read More

Adsorption of Copper, Zinc and Lead Metal Ions from Aqueous Samples Using Fe3O4 Magnetic Nanoparticles Modified with Alizarin Red S

Sedigheh Kamran

Volume 4, Issue 2 , September 2017, Pages 22-32

Abstract
  Fe3O4 magnetic nanoparticles modified with alizarin red S (ARS-Fe3O4) were used for the removal of several metal ions from aqueous solution. The mean size and the surface morphology of the nanoparticles were characterized by TEM, XRD and FTIR techniques. Adsorption studies of mentioned metal ions were ...  Read More

Quantitative Determination of Clavulanic Acid in Human Plasma by Liquid Chromatography–Tandem Mass Spectrometry and its Application to Pharmacokinetics Study

Milan Modi; Punit Parejiya; Nikunj Patel; Rakesh Sutariya

Volume 4, Issue 2 , September 2017, Pages 33-41

Abstract
    A rapid, selective and sensitive liquid chromatography–tandem mass spectrometry (LC–MS/MS) assay has been proposed for the determination of Clavulanic acid (CA) in human plasma using Diclofenac sodium as internal standard (IS). The analyte and IS were extracted from human plasma via ...  Read More

Screening and Optimization of Experimental Condition for the Determination of Silver Based on Switchable Solvent Liquid Phase Microextraction

Fereshteh Heydari; Majid Ramezani; Nasim Bayat; Maryam Ghalenoei

Volume 4, Issue 2 , September 2017, Pages 42-49

Abstract
    A novel switchable-hydrophilicity solvent based liquid phase microextraction (SHS-LPME) coupled with flame atomic absorption spectrometry has been applied for preconcentration and extraction of Ag(I). In this study, Triethylamine (TEA) was selected as switchable solvent. The Ag (I)-1-(2-pyridylazo)-2-naphthol ...  Read More
