摘要：
A new method for precise determination of H(2)O(2), based on perturbation of the [Cu(Me(6)[14](4),11-diene N(4))](2+)-NaBrO(3)-malic acid-H(2)SO(4) oscillating reaction system caused by different amounts of H(2)O(2) has been developed. Under optimum conditions the amplitude of potentiometric oscillations decreased linearly with the logarithm of H(2)O(2) concentration in the range 9.0 x 10(-6)-1.80 x 10(-4) mol L(-1), with correlation coefficient of 0.9992. Relative standard deviation (RSD) of five determinations of 1.1 x 10(-1) mol L(-1) H(2)O(2) was 0.6%.
