By applying the principle of ion-chromatography method for testing ammonia content in electrostatic precipitator fly ash, tests to optimize detecting conditions is carried on. It is concluded that the main factors influencing ammonia content in fly ash are pH of solution, mixing time, water and ash ratio and so forth. Af-ter optimal test condition is obtained, repeatability test and adding standard recovery rate test are conducted. The results show that ion-chromatography method is of high precision and accuracy in testing ammonia con-tent in electrostatic precipitator fly ash and it can be used to monitor ammonia escape in desulfurization system.
