查询词典 method of difference

The oxidable potential difference of DA and AA was about 184 mV at Poly-Evans Blue modified electrode. So it is used to simultaneously determine the DA and AA without any interference. The interference of other components could be efficiently eliminated at the modified electrode, and this method can be used for determination of DA and AA in real sample with satisfactory results.
