摘要：

The electrochemical behaviour of bilirubin in Tris-HCl buffer solution at a hanging mercury drop electrode was investigated. The adsorption phenomena were observed by differential-pulse adsorption voltammetry (DPAV). In 0.01 mol l-1 Tris-1.2 x 10(-3) mol l-1 HCl buffer, the detection limit and the linear range of bilirubin were 2 x 10(-10) and 1 x 10(-9)-4 x 10(-7) mol l-1 by DPAV, respectively. The influences of light and oxygen on bilirubin were also studied. The method was applied to samples of refined bilirubin.
