| Abstract: | The content of lead in fly ash was determined by microwave digestion atomic fluorescence spectrometry. Emphasis was focused on the influence of amount of potassium ferricyanide and the addition of hydroxylamine hydrochloride. Experimental results showed that the addition of potassium ferricyanide improved Plumbanc generation, Hydroxylamine hydrochloride played restraining role. The detection limit was 0.39 ug/L and the recovery rate was 83.6%-101.3%. This method has good reliability and is suited for the determination of lead in fly ash. |
