Cold cyanolysis standard curve for persulfide quantification
(A) Representative UV-Vis spectra from the cold cyanolysis standard curve (1 mM SCN-, black; 2 mM SCN-, red; 2 mM SCN- in, blue; 4 mM SCN- in, green). The absorbance at 460 nm is indicated by a dashed gray line. Black line corresponds to the 0.5 mM standard, red line corresponds to the 1 mM standard, blue line corresponds to the 2 mM standard and the green line represents the 4 mM standard.
(B) Triplicate dataset of the standard curve at 460 nm fitted to a linear equation. The concentrations and colors from panel A match the square points plotted in panel B.
