| Abstract: | The interference with Mn matrix in determination of trace selenium was studied,the instrument parameters was optimized.The sample was dissolved in dilute nitric acid,the interference from matrix was eliminated with matrix matching,and then selenium was determined by inductively coupled plasma-atomic emission spectrometer(ICP-AES)conveniently.The result was tally with the results of GB/T 86654.6-88 phenyl hydrazine hydrochloride-iodine method.This recovery was 97%～105%,the precision of 2.5%～7.23% and the detection limit of 0.0261μg/mL,respectively. |
