ABSTRACT
In NH4Cl-NH2CH2NH2-EDTA (pH = 9.0) supporting electrolyte containing cupferron, chromium( Ⅵ) complex with cupferron has a rather sensitive adsorptive wave. The reduction peak potential is -1.45V. The determination limit is 9,6?10-10mol/L. This method has been successfully used to samples of tea, grain and water.
