High impact information on tetraethylboron

  • The isotopic composition of the mixed spike was determined by gas chromatography/ICPMS after aqueous ethylation using sodium tetraethylborate, and the determination of the concentration of the different species in the spike was performed by means of reverse isotope-dilution analysis using natural MBT, DBT, and TBT standards [1].
  • The method has been adapted for the simultaneous determination of mono-, di- and tributyltin species (MBT, DBT and TBT) after derivatization with sodium tetraethylborate in water and sediment samples [2].
  • The stabilizers were then hydrolyzed to the chloride forms, by treatment with 6 mol L(-1) HCl, then derivatized with sodium tetraethylborate (NaBEt(4)) in 0.2 mol L(-1) sodium acetate buffer (pH 4.5) at 50 degrees C. HS-SPME was performed with a fused-silica fiber coated with a 100-mum film of polydimethylsiloxane (PDMS) [3].
  • A GC-ICP-MS method based on extraction and alkylation of butyltins with sodium tetraethylborate was used to quantitatively assess the fate of these analytes in solutions and sediments following exposure to gamma-irradiation [4].
