Abstract: The analytical methods, using microwave plasma torch as excitation light source, argon as supporting gas and peneumatic nebulization sampling system, for Cu and Fe metal elements in cucumber-seed oils by Microwave plasma torch atomic emission spectrometry (MPT-AES) was studied. The detection experimental parameters, including microwave forward power,flow rate of carrier gas and support gas, acid concentration of HNO3 and HClO4 on the detections were investigated, and coexistent ions to the emission strength of metal elements of Cu, Fe were optimized. The detection limits of mass concentration of Cu, Fe were 5.3 and 22.1 ug / L, RSD (n=6) <5%, and measured their recovery rates were 97.4% and 102.8%, and the accuracy of the method was identified by standard addition recovery. The results show that, the Cu, Fe of cucumber-seed oil of MPT-AES determination is simple, high degree of automation, low running costs, quickly and accurately. Therefore it is a well-established analytical method.
