Table 1 Determination of Se (VI) in pH 7

From: Fast and simple selenium speciation by solid phase extraction and laser-induced breakdown spectroscopy

Sample Concentration of Se (VI) in sample solution (mg/kg) Result by LIBS (mg/kg) Recovery (%)
50 mg/kg Se (VI)a 50.0 49.2 ± 2.7 98.5
100 mg/kg Se (VI)b 100.1 101.9 ± 2.0 101.8
  1. a25 mg/kg Se (IV) + 25 mg/kg Se (VI) sample was prepared, and Se (IV) was oxidized to Se (VI)
  2. b50 mg/kg Se (IV) + 50 mg/kg Se (VI) sample was prepared, and Se (IV) was oxidized to Se (VI)
