| 摘 要： | 电厂凝结水中氨含量的准确测定,是确保凝结水精处理系统运行周期及防止系统腐蚀的重要保障,用钠氏试剂分光光度法和电极法对电厂凝结水中氨含量进行了测定,并对两种方法的测定值进行了比较,结果显示两种方法的准确度、精密度都令人满意。而铵离子选择性电极因其测定简单、误差小、无毒环保等优点,更适用于电厂实验室凝结水氨含量的测定中。

| Abstract: | The accurate determination of the ammonia content in power plant condensation is an important guarantee to ensure the condensate polishing processing system running cycle and to prevent the system from corrosion. Ammonia content of condensation on the power plant using Nessler＇s reagent colorimetry method and electrode method were determined, and the measured values of the two methods were compared, results showed that the accuracy and preci- sion of the two methods is satisfactory. With the advantages of simple operation, small error and non-toxic, ammonium ion selective electrode determination is more suitable for the determination of ammonia content of water condensation in the power plant laboratory. |
