Abstract
A simple and sensitive capillary elecrophoretic method has been developed for the separation and determination of Nabam and NaDDC in boric acid buffer by direct UV absorbance detection at 254 nm. The separation is dependent on pH and nature of the buffer. In this method the detection limits (S/N = 3) are 1.56 × 10−6 mol/L and 2.48 × 10−6 mol/L and the linear calibration range is three orders of magnitude for Nabam and NaDDC, respectively. The method has been successfully applied for the analysis of wheat samples spiked with Nabam.
