| Abstract: | A catalytic spectrophotometric method based on the oxidation of Congo red with H_2O_2 by means of Cu (II) as catalyst for the determinition of trace Cu(II) has been in vestigated. The sensitivity of the method is 3.5×10~(-11) g/mL, the linear respondence is in the range of 0-24 ng/mL. The effect of foreign ions has been studied and the method shows remarkable selectivity. The proposed method has been applied to determine animal serum copper with satisfactory results. |
