“…Classification by Ni/V ratios has been used widely to distinguish sources of crude oil between marine and terrestrial environments, most recently in crude deposits in Nigeria, Russia, Venezuela and South Africa (Akinlua et al, 2015;Lopez et al, 2015;Ogunlaja et al, 2014;Yasnygina et al, 2015).…”

“…On the other hand the humic type has comparatively low V and Ni contents at a high Fe content and low V/Ni ratio (<1) (0.68 and 0.54 for Basrah and Khanaken, respectively). Based on the above conceptions, the organic (biogenic) component has a continental origin (humic type) (Basrah and Khanken fields) (Yasnygina et al, ).…”

A method for digestion of light and medium Iraqi crude oils (Basrah and Khanaken oils) using microwave‐induced combustion (MIC) in closed vessels is described for the determination of Hg, Au, Cu, Al, Ca, Co, K, Mg, Si and Sr by inductively coupled plasma optical emission spectrometry (ICP–OES) and Mo, Ti, Mn, Li, Se−1, Rb, Ag, Ba, Pb, As, Cd, Cr, Fe, Ni, V and Zn by inductively coupled plasma mass spectrometry (ICP–MS). Upon using MIC it was possible to obtain lower limits of detection by ICP–MS and also by ICP–OES compared with those obtained by microwave‐assisted digestion. The MIC was the best choice with regard to the possibility of using dilute nitric acid as an absorbing solution, which is important to minimize the interference encountered by ICP–MS and ICP–OES.The physicochemical parameters and some contaminants of crude oil samples were analyzed to classify and assess the quality of the crude oils. This study determines the viability of the use of Fourier transform infrared spectroscopy as an alternativee to traditional petroleum geochemical methods for crude oil characterization. The infrared fingerprints agree with the results obtained from GC–MS analysis.

“…There are works on the autoclave decomposition of oils for the determination of their trace element composition, for example, autoclave mineralization of oil in a mixture of HNO 3 with H 2 O 2 [4]. Acid decomposition is the most affordable and common method of sample preparation used for the determination of trace elements in oils [5,6]. However, it is time-consuming and bears some risk of losing volatile element compounds in the digestion of the sample.…”

A combined method of sample preparation for the determination of the total element composition of oils

A comprehensive approach to the determination of the elemental composition of oils (including those with a viscosity of 5000 mm 2 /s) is proposed. It ensures the determination of the most elements present in oils using two versions of sample preparation, autoclave decomposition of oil samples and extraction preconcentration of elements from oil into an aqueous solution on rotating coiled columns (RCCs). The application of RCCs in the elemental analysis of oil ensures the preconcentration of a number of trace elements from oil (including rare-earth elements) and the determination of their concentrations at a level of ng/kg. The preconcentration factor of trace elements from oil using an RCC depends on the volume of oil sample pumped through a constant volume of the stationary phase (acid solution) retained in the column and on the speciation of elements in the oil.
