| 摘 要： | 探讨了化学探头法和荧光光谱法测定水中溶解氧的关系。分别用F检验和t检验对两组数据进行了比较,结果表明两组数据的精密度和系统误差都没有显著差异,两种方法测定溶解氧的相对标准偏差(RSD,n=9)分别为0.35%,0.33%。进而又探讨了溶解氧与NaCl含量、温度之间的关系,结果表明溶解氧含量随NaCl含量的增加、温度的升高而逐渐降低。

| Abstract: | The relationship between the electrochemical probe method and the fluorescence method for the determination of dissolved oxygen in water was discussed. F-test and t-test were applied to compare the precision and systematic errors of the two methods by two groups of experimental data. The results showed that they were not significant differences. The relative standard deviations (RSDs, n=9) of the two methods were 0.35% and 0.33%, respectively. The relationship between dissolved oxygen and temperature, NaCl content were also discussed It is clear that the dissolved oxygen content increase with the increase of the content of NaCl and with the decrease of temperature . |
