AbstractModified magnetic nanoparticles (MNPs) of the “core–shell” type have a potentially wide range of applications in various fields of scientific activity, in particular, in analytical chemistry. These applications are based on the sorption properties of magnetic nanoparticles, which are determined by the surface structure of the nanoparticle. ...

AbstractA scheme is proposed for the rapid dynamic sorption preconcentration of volatile organic compounds in the gas chromatographic analysis of air, based on a change in the configuration of the sorption layer in a transition from the sorption to the thermal desorption of analytes. The sorption extraction of analytes is carried out in a wide sorp...

AbstractA method for the quantification of a mixture of fluorescent antibiotics with broad, highly overlapped excitation and emission spectra is proposed. The method enables the simultaneous determination of sarafloxacin, flumequine and ofloxacin by using the fluorescence excitation-emission matrix and performing two different scans, namely, a line...

AbstractAs a new type of multifunctional material, metal−organic frameworks (MOFs) have a wide application prospect in the field of chiral separation. In this study, a homochiral MOF [Ni(S-mal)(bpy)]n was synthesized by the reaction of S-malic acid (S-mal) and 4,4′-bipyridine (bpy) with nickel acetate. The homochiral MOF [Ni(S-mal)(bpy)]n was explo...

AbstractThe sorption and desorption of a number of hydrophilic organophosphorus substances (alkylphosphonic and O-alkylalkylphosphonic acids, glyphosate, glufosinate, and aminomethylphosphonic acid) from an aqueous medium on porous graphitized carbon (Hypersep Hypercarb sorbent) was studied. It was shown that the indicated analytes are quantitative...

AbstractThe order of laying down homogeneous intersecting strokes of ball-point inks has been assessed using a range of different spectroscopic and analytical techniques for recent inks and for inks with a time difference of 4 years. These techniques are infrared reflectance photography with luminescence, fluorescence micro-spectrophotometry, Fouri...
