我们优化了电极的测试条件并发现在最优的实验条件电极的氧化峰电流与其浓度

We optimized the test conditions of the electrode and found that there is a good linear relationship between test between the measured minimum / L oxidation peak current and concentration optimal experimental conditions electrode is 2.0 × 10 -7 ~ 2.0 × 10 -5 mol The detection limit was 2.5 × 10 -8 mol / L (S / N = 3). EE2 milk and the sensor for detecting the residual water samples, the recovery was 80.6 ~ 104%, RSD ≤ 6.0%.

We optimized the test conditions of the electrode and the current optimal experimental condition electrode oxidation peak current and its concentration in 2.0 x 10 -7 to 2.0 to 2.0 to 10 -5 mol/L there is a good linear relationship, the minimum detection limit measured by the experiment is 2.5 x 10 -8 mol/L (S/N x 3). The sensor is used to detect residual EE2 in milk and water samples, with a combined recycling rate of 80.6 to 104%, and RSD s 6.0%.

We have optimized the test conditions of the electrode and optimized the experimental conditions. There is a good linear relationship between the oxidation peak current of the electrode and its concentration in the range of 2.0 × 10-7 ~ 2.0 × 10-5 mol / L. the minimum detection limit is 2.5 × 10-8 mol / L (s / N = 3). The sensor was used to detect the residual EE2 in milk and water samples. The recovery of standard addition was 80.6 ~ 104%, RSD ≤ 6.0%.
