Abstract: The spectral and voltammetric properties of bilirubin ditaurate conjugate in aqueous' solution were determined by employing the indicated analytical techniques. The wavelength of maximum absorbance was found to be 450nm. The molar absorptivity was determined from plots of absorbance at 450nm versus concentration to be 49,900 cm-l M-l and was found to decrease significantly over a time period of 22 days. A bilirubin oxidation wave was observed at a peak potential of 0.S8V (vs. AgCl/Ag). This wave exhibited the expected scan rate and concentration dependances at a glassy carbon working electrode. Results indicated that the oxidation of aqueous bilirubin conjugate is a simple, diffusion-controlled electrode reaction.
