Abstract：Determination of silicon content in aluminum alloys using ultrasonic sealed digestion-inductively coupled plasma atomic emission spectrometry was established.By optimizing the digestion conditions of the sample,screening the ultrasonic intensity,sealing conditions,ultrasonic temperature,ultrasonic time,and acid concentration,and selecting appropriate analytical spectral lines,the medium content of silicon element was determined.Precision and accuracy experiments were conducted on aluminum alloys ZLD105,ZBY5291 and ZBY5091 with different silicon contents.The relative standard deviation (SRSD) was 0.3%~0.7%, and the recovery rate was 98.9% ~101.0%.This method is low-cost,fast,accurate,and convenient for analysis,and can be applied to actual sample testing.
