Elemental analysis of Egyptian crude oils by INAA using rabbit irradiation system at ETRR-2 reactor.
Instrumental neutron activation analysis (INAA) using rabbit irradiation system at ETRR-2 reactor was utilized to analyze some elements namely Na, Mg, Al, Cl, V, Mn, In, and Br in four different crude petroleum samples from different oil fields in the Suez-Gulf region of Egypt. The INAA was performed by four different standardization methods. Namely absolute, single comparator based on effective cross section concept, single comparator based on k(0,Au) factors, and that based on k(0,ic) factors defined versus any suitable internal comparator method. A FORTRAN computer program was written to calculate the extracted concentrations by these methods. A reasonable agreement between the obtained results was noticed.
