    A differential pulse polarographic method has been developed for the determination of Mn(II) and Zn(II) in biological and human hair samples using newly synthesized reagent 2,2'-{benzene-1,2-diylbis(nitrilomethylylidene]}diphenol after preconcentration and separation using amberlite XAD-1180 in the range of pH 8.0-10.0. The sorbed elements was subsequently eluted with 10mL of 2.0 M HCl elutes was analysed by differential pulse polarography (DPP). The interference of foreign ions has also been studied. Effects of various instrumental parameters are investigated and received conditions are optimized. The limits of detections were found to be 0.0026 and 0.0032 μg mL-1 for Mn(II) and Zn(II) respectively by applying a preconcentration factor ~30. The proposed enrichment method was applied successfully for the determination of Mn(II) and Zn(II) in biological and human hair samples. The proposed method was compared with reported methods in terms of Student’s ‘t’-test and Variance ratio ‘f’-test which indicates that there is no significant difference between proposed and literature method at 95 % confidence level.
