| Abstract: | The behaviour of the complex of zinc with Eriochrome blue black R(EBBR),adsorbed on HMDE has been investigated by derivative adsorption chronopot entiometry inNH 3/NH 4Cl.The dependence of the peak height on the d t /d E vs.E curve on the preconcentration time,the pH of solution,the constant reducing current and ratio of concentration of zinc and EBBR are discussed.This method has been used to determination of zinc in human hair. |
