A Simple and Fast Method for Magnetic Solid Phase Extraction of Ochratoxin A

A Novel Magnetic Nano-hybrid as a Sorbent for Solid-phase Extraction-spectrophotometric Determination of Methyl Violet 10B Dye

In this research, the magnetite polystyrene maleic anhydride (MPSMA) was synthesized and structure and morphology characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy techniques. The obtained nano-structured inorganic material was employed as a novel magnetic nanosorbent for separation and pre-concentration of Methyl violet (10B) dye from aqu...

Synthesis and Application of Novel Modified Magnetic Nanocomposite for Solid Phase Extraction of Thallium(I) Ions

In this paper, magnetically multiwalled carbon nanotubes (MMWCNTs) nanocomposite modified by methyl-2-[2-(2-2-[2-(methoxycarbonyl) phenoxy] ethoxyethoxy) ethoxy] benzoate was applied for magnetic solid-phase extraction (MSPE) of thallium(I) ions. Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) spectrometry and vibrat...

Spectrophotometric Determination of Mefenamic Acid in Biological Samples Using Magnetic Iron Oxide Nanoparticles as a Sorbent for Solid Phase Extraction

This work investigates the potential of magnetic Fe3O4 nanoparticles as an adsorbent for separation and preconcentration of trace amounts of mefenamic acid in aquatic and biological samples, prior to spectrophotometric determination. The magnetic iron oxide nanoparticles (MIONs) were synthesized by mixing of ferrous and ferric chlorides. The possible parameters affecting the enrichment were opt...

A fast and simple method for modeling of oil swelling in Co2 injection

In this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. A moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by Co2 diffusion through a blocking water phase. The results of this modeling are compared with experimental results of a 2D glass micromodel experiment. Although, the solution method is applie...
