Capillary electrophoretic determination of ferric dimethyldithiocarbamate (ferbam) using 1,10-phenanthroline

A simple and sensitive capillary : elecrophoretic method has been developed for the determination of Ferbam (ferric dimethyldithiocarbamate) in acetate buffer after its complexation with I, 10-phenanthroline and as iron(II)-1,10-phenanthroline complex. The determination is dependent on the pH and the nature of the buffer solutions. In this method the detection limit (S/N = 3) is 1.87 x 10(-6) mol L-L (0.78 mg/kg). The relative standard deviation for the analysis of 50 mug mL(-1) was found to be 2.4%. The method has been successfully applied for the analysis of wheat samples spiked with Ferbam. The applicability of capillary electrophoresis as a useful tool for the rapid analysis of Ferbam is demonstrated.
