This article presents the method of extraction-preconcentration of Lead, Cadmium, and Nickel ions from food samples using the Ghezeljeh montmorillonite nanoclay (Geleh-Sar-Shoor) as a new native adsorbent in batch single component systems. The extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (SPE) method followed by atomic abs...

In this study, a dispersive liquid–liquid microextraction method using an extraction solvent lighter than water has been developed for the extraction and preconcentration of cholecalciferol and calcifediol from plasma samples followed by high performance liquid chromatography determination. Initially, acetonitrile and sodium chloride (NaCl) are added into the plasma as an extraction solvent and...

The structure of complex organic solutions based on N,N,N’,N’-tetraoctyldiglycolamide (TODGA) used in actinide separation processes were characterized after water and neodymium extraction. phases using FTIR spectroscopy, ESI-MS spectrometry, Small Wide Angle X-ray Scattering (SWAXS) molecular dynamic simulations. role the “phase modifier” like 1-octanol (used innovative SANEX process) or “co-ex...
