| Popis: | An analytical method for the determination of Na, Mg, Ca, Fe, V, Ni and Cu in crude oil by inductively coupled plasma-atomic emission spectrometry, using microwave ashing as samples pre-treatmentmeans was establelished. The crude oil program of microwave ashing and sample weight were studied. Meanwhile, the operative conditions of inductively coupled plasma-atomic emission spectrometry were optimized. The detection limits were 0.07, 0.01, 0.01, 0.01, 0.02, 0.04 and 0.03 mg/kg for Na, Mg, Ca, Fe, V, Ni and Cu, respectively. The average recoveries between 84.5%and 96.6% , and the RSD between 2.1% and 6.9% for determination results of metal element content of china import 80 kinds of crude oil from Saudi Arabia, Angola, Iran, Russia, Sudan, Oman, Iraq, Kuwait, Venezuela, etc.. |
