title: Electrochemistry of the interaction of furazolidone and bovine serum albumin.
abstract: The electrochemical behavior of the interaction of furazolidone (Fu) with bovine serum albumin (BSA) was investigated by cyclic voltammetry and differential pulse voltammetry at a glassy carbon electrode. Fu shows an irreversible reduction at -0.34 V in pH 4.0 Britton-Robinson buffer (B-R) buffer-10% DMF solution. After the addition of BSA into the Fu solution, the reductive peak currents decreased without any significant shift of the peak potential and the appearance of new peaks. The electrochemical parameters of the interaction system were calculated in the absence and presence of BSA. This electrochemical method was further applied to the determination of BSA samples and the results were in good agreement with the traditional cellulose acetate electrophoresis. The linear dynamic range was between 10.0 and 80.0 mg l(-1). The detection limit was 7.6 mg l(-1) and the recoveries were obtained from 97.0% to 104.0%.
