摘要: A method for the determination of Cd,Pb and Sr by microwave plasma torch(MPT)atomic emission spectrometry(AES)was developed.The samples were introduced into the MPT with an electrothermal vaporization(ETV)device.The effects of some experimental conditions on the determination of Cd,Pb and Sr were examined.The effects of easilyionized elements on the emission intensity of Cd,Pb and Sr were studied in detail.The detection limits for Cd,Pb and Sr are 2.4,4.0 and 1.3 ng/mL,respectively.
