Title

ADSORPTIVE STRIPPING DIFFERENTIAL PULSE VOLTAMMETRY FOR DETERMINATION OF TRACE AMOUNTS OF RIBOFLAVIN IN HUMAN PLASMA

Pages

  27-34

Abstract

 A new adsorptive anodic differential pulse stripping voltammetry method for the direct determination of RIBOFLAVIN at trace levels in HUMAN PLASMA is proposed. The procedure involves an adsorptive accumulation of RIBOFLAVIN on a hanging mercury drop electrode (HMDE), followed by oxidation of adsorbed RIBOFLAVIN by voltammetry scan using differential pulse modulation. The optimum conditions for the analysis of RIBOFLAVIN are pH=6.5 using borate buffer, accumulation potential of -700 mV (vs. Ag/AgCl), and accumulation time of 70 s. The peak current is proportional to the concentration of RIBOFLAVIN, and a linear calibration graph is obtained at 0.01-0.90 mgml-1. A relative standard deviation of 0.52% (n= 3) was obtained, and the limit of detection was 6 ngml-1. The capability of the method for the analysis of real samples was evaluated by determination of RIBOFLAVIN in spiked HUMAN PLASMA with satisfactory results.
