Competitive Zincon binding titrations at pH 7.5 for [Hg(II)]S(TRIL9CL23H)3− in the forward (Zn(II)pep3 + Zincon) and reverse (Zn(II)Zi + pep3) directions. a) Representative UV-Vis spectra for the titration in the forward direction and b) in the reverse direction. c) Plot of absorbance at 620 nm as a function of increasing [Zincon] for the forward titration and d) as a function of increasing [pep3] for the reverse titration.
