Determination of trace metoclopramide by anodic stripping voltammetry with nafion modified glassy carbon electrode.
A novel method is described for determination of metoclopramide (MCP) by second-derivative adsorptive anodic stripping voltammetry with a nafion-modified electrode. The stripping peak current is proportional to the concentration of MCP over the range 1.2x10(-9)-4.6x10(-7) M. The detection limit is 8.0x10(-11) M with 4-min accumulation. The method has been successfully applied to the determination of MCP in human serum.
