摘要
介绍用电极法测灰中氨含量,并通过对比对样品的不同处理方法,确定最能体现样品中氨含量的最佳处理方法。实验表明,粉煤灰溶解的最佳灰水比为1∶10,最佳搅拌时间为10 min,滤纸中含有一定量的氨,在检测时需注意去除本底值。
This article introduces a new method for testing ammonia content in fly ash,which is called electrode method. Additionally,several treatments for the samples were compared. From the experiments we can tell that the ammonia content can be best presented when fly ash water ratio is 1 ∶ 10,best stirring time is 10 min. To make sure an accurate result,we should consider the ammonia content of the filter paper.
