| Abstract: | It was determined that 4-(2-thiazolylazo)resorcinol(TAR)and the chelates of iron,cobalt and nickel with TAR can be oxided at a glassy carbon electrode.The above chelates andTAR were separated on a spherisorb ODS column with a mobile phase of methanol-water(55/45,V/V) containing 0. 01 mol/L Na2HPO4-KH2PO4 buffer(pH 7.0) and were detected at 0.86V. The calibration graphs were rectilinear from 0.1-5 ppm,0. 01-5 ppm,0.08-1 ppm for iron, cobalt and nickel, respectively. The detection limits were 0.8,0.2,0. 8 ng for iron,cobalt and nickel respectively. The method has been applied to the analysis of hair samples. |
