The emergence of mass-spectroscopy with inductively-coupled plasma (ICP-MS) made it possible to study the microelement composition of crude oil and its derivatives with the limit of detection (LOD) at the ppt level. We have studied the crudes from West Siberian (Shaimsky, Sredneobsky and Oktyabrsky regions) and Tatarstan Romashinskoye oilfields with the ICP-MS method to detect 50 rare, rare-earth, and other microelements. The elemental composition is reasonably comparable to their concentrations in ultrabasites whereas the contents of most of the elements are low to the limit. On the diagrams of rare-earth elements, one can see the prevalence of light lanthanides and positive europium anomaly. Increased content of platinoids was found in Tatar oils; in some cases, the concentration of ruthenium reaches 0.06 g/t. The study shows that studied crudes have a specific microelement composition. Based on the elevated contents of transit elements and platinoids, a conclusion was made about the “ultrabasic” geochemical–metallogenic specialization of studied petroleum systems and the assumption about its origin was proposed.

The study shows that crude oils have a specific microelement composition that stands out from other geological systems.

Influence of sample pretreatment on the analysis of the high contents of rare earth (REE) and high field strength (HFSE) elements in geological samples by inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS) was studied. The rocks and rich ores of the Tomtor Nb-REE deposit were explored. Complete dissolution of the geological samples with a high content of “refractory” minerals has been achieved using fusion with a sodium peroxide. The results obtained by ICP-AES and ICP-MS after chemical dissolution are comparable with the results obtained by the XRF-SR without chemical pretreatment

ABSTRACTA method has been developed to analyze mercuric iodide (HgI2) for elemental contamination using Inductively Coupled Plasma/Mass Spectroscopy (ICP/MS). This paper will discuss the ICP/MS method, the effectiveness of purification schemes for removing impurities from Hgl2, as well as preliminary correlations between HgI2 detectorperformance and elemental contamination levels.

A novel approach of rare earth elements (REE) determination in crude oil is suggested. Special application of countercurrent chromatography (CCC) is used as a sample pretreatment tool. An oil sample is continuously pumped through the rotating coil column (RCC) as a mobile phase, while an aqueous phase (nitric acid solution) is retained as a stationary phase. Two phases are kept well mixed and agitated, but there is no emulsion at the interface under the chosen conditions. Special features of CCC give an opportunity to vary the volume of oil samples to be analyzed from 10 mL to 1 L or more. Trace metals are preconcentrated into 10 mL of stationary phase (acidic solutions) pumped out of the column so that analysis can be easily determined with inductively coupled plasma mass spectrometry (ICP-MS) without additional sample preparation procedures. Optimal concentration of nitric acid in the stationary phase for preconcentration of REE from oil by CCC has been investigated. The combination of CCC with ICP-MS gives the possibility to develop a rapid, reliable, and accurate method of trace metal including rare earth elements (REE) determination in crude oils and oil products. Such method could be an alternative for unexpanded and expensive neutron-activation analysis (NAA).

Upper Silesia is the most transformed by humans of the Polish territories. As a result of mining, urbanization and other industrial activities, irreversible changes have taken place in the environment. In this paper, the method of collecting, preserving, storing and preparing samples from four Silesian rivers was optimized. Silesian sediment and river water samples are a challenge for the analyst, because they have complex matrices and high content of chlorides coming from the discharges of saline water. This study concerned determination of Sb(III), Sb(V), As(III), As(V), MMA, DMA, AB, Cr(III) and Cr(VI) with high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). The following columns were used: Dionex Ion Pack AG7 to determine chromium forms, Hamilton PRP-X100 to separate antimony species and Dionex Ion Pack AS7 to determine five chemical arsenic forms. The methodology used allowed for elimination of interferences during analysis of highly saline and complex samples and ions separation directly without adding any complexing compounds. Depending on the analytes, full separation was obtained within 3–9.5 min. The sediment sample extraction and determination were validated (recovery, limit of detection, repeatability and uncertainty) with the certified reference materials (CRMs). The optimized methodology allowed for study of mobility and seasonality changes of As, Sb and Cr species in the river environment.
