| 中文摘要: |
| 建立了一种基于自动电位滴定技术的脐橙叶片中氯含量的快速检测方法。该法采用稀硝酸浸提脐橙叶片中氯，然后用自动电位滴定法快速测定溶液中氯含量，并考察了方法的测定条件、精密度和准确度。该方法的检出限为0.6249mg/L，加标回收率为94.85%～102.96%，相对标准偏差小于3.0%，故该法适于脐橙叶片中氯含量的快速分析。 |
| 英文摘要: |
| A new method for rapid determination of chlorine content leaf of navel orange was developed. The chlorine in leaf was extracted by dilute nitric acid and determined by automatic potentiometric titration. The determination condition was optimized, and the accuracy and precision of the method were studied. The results showed that the detection limit was 0.6249mg/L, the recovery was 94.85% ~102.96%, and the RSD was within 3.0%. The proposed method has been successfully applied to determine the chlorine content in leaves of navel orange from southern Jiangxi. |
