    • note
    • Although the reaction mixture is transparent at λ > 300 nm under the studied conditions, at λ = 300-360 nm, the analysis is complicated by absorbante changes due to the formation of Cys-Cys.

    • note
    • 6 Not less than 95% of Cr(VI) was recovered by this method. The formation of Cys-Cys was shown qualitatively by IR spectroscopy. However, the quantitative determination of Cys-Cys is difficult because of its small concentration relative to unreacted Cys and its possible additional formation by autoxidation of Cys during the analytical procedures.

    • More detailed studies of the region 350-380 nm (kinetic curves were acquired every 1 nm) did not reveal any shift of absorbance maximum (372 nm) for B in comparison with A.
