| 摘 要： | 在0.3 V~0.7 V氧化电压范围内,用差分脉冲伏安法测定无锌汽轮机油中芳胺型抗氧剂时可消除酚型抗氧剂的影响,同时用正交实验优化了差分脉冲伏安法的扫描参数。优化后的差分脉冲伏安法的检测含量更低,灵敏度更高,回归分析的线性相关系数为0.9998。

| Abstract: | The effects of phenolic antioxidants could be eliminated while the aromatic amine antioxi dants were determined by differential pulse Vohammetry in range of 0.3 V~0.7 V oxidative Voltage, and the sweep pa- rameters of differential pulse Vohammetry were optimized by orthogonal experimental at same time.The minimum detecting content of optimized differential pulse Vohammetry was lower, the detecting sensitivity was higher, and the linear correlation coefficient of regression analysis was 0.9998. |
