摘要
本文希望根据纳氏试剂法测定氨含量的原理,用水溶解飞灰中的氨,来测定电厂飞灰中的氨含量。在试验不同的条件后,确定最优条件。再通过纳氏试剂分光光度法与离子色谱法的结果比对,并进行重复性测试和加标回收率试验。实验结果表明,用纳氏试剂分光光度法测定电厂飞灰中氨含量的结果准确、可靠,可作为分析电厂飞灰中氨含量的一种方法。
In this paper, the ammonia content in fly ash of power plant can be determined by dissolving the ammonia in fly ash with water according to the principle of determination of ammonia content by nessler’s reagent method. After testing different conditions, determine the optimal conditions. Compared the results of the nessler’s reagent method and ion chromatography, then the repeatability test and the standard recovery test were carried out. The experimental results show that the determination of ammonia content in fly ash of power plant by spectrophotometry with Nessler reagent is accurate and reliable, and can be used as a method for the determination of ammonia content in flying ash of power plant.
