This paper reviews the use of inductively coupled plasma mass spectrometry (ICP-MS) for sulfur analyses, covering articles published between January 2015 and April 2023. The ICP-MS instruments reported in the articles were classified as quadrupole ICP-MS, tandem quadrupole ICP-MS, high resolution ICP-MS, and multi-collector ICP-MS, each accounting for over 20% of the articles. Each type of ICP-MS instrument achieved detection limits < 1.0 ng/g. Laser ablation and chromatography hyphenated ICP-MS accounted for > 30% of the articles, with special attention paid to direct/imaging and speciation analyses. The leading research field in sulfur analysis is geology, followed by biology, environment, food/feed, and energy. Determination of sulfur concentrations, chemical speciation analysis of sulfur compounds, and sulfur isotope analysis accounted for approximately 30-40% of the articles. The most frequently measured sulfur isotope was 32 S, followed by 34 S and 33 S, whereas one article reported the measurement of 36 S. Selected topics of sulfur analysis using ICP-MS in research fields, hyphenated instruments, and typical applications are also introduced.www.at-spectrosc.com/as/article/pdf/2023187

“…The sulphur content was 0.005% mass, which is a bit higher than the ASTM standard of 0.002% mass, but lower than the EN standard of 0.02% mass. Compared with fossil fuels, one of the most important advantages of biodiesel is its low emissions of sulphur compounds into the atmosphere [72]. The cloud point was measured to be 0 • C which is less than the ASTM standard of −2 to −12 • C, while the pour point of the biodiesel from the study was −2 • C compared to the ASTM standard of −15 to −16 • C. The values of the cloud and pour points as indicated are higher than the standards, which is a disadvantage for the resulting biodiesel.…”

Dates are an important food source in many countries that produce different types of dates. Dates have a significant amount of waste, either from planting or eating them. A large amount of seeds are produced from eating it. This study is considered to explore the quantity and the quality of biogas produced from the Sagai date seeds through the anaerobic digestion process (AD) before and after oil extraction and exploitation of oil in biodiesel production. In addition, the study aims to tests the resulted digestate from the AD process. This test was performed to ensure that the digestate contains the three basics elements (N, P and K) to be used in agriculture. In its preparation, the date seeds were ground after washing via a grinding machine without exposure to any other treatment process. Design of Experiments (DOE) was applied in determining the effect of temperature, volatile solid and sludge quantity on the resulted biogas. The energy balance at the optimum results was calculated. The highest biogas volumes from the AD of date seed before and after oil extraction were 4140 cc and 3534 cc, respectively, at 37 °C, 4.2 g-VS and 50% sludge quantity. While the highest methane/g-VS were 1143.8 cc/g-VS and 949.6 cc/g-VS, respectively, at 37 °C, 1.1 g-VS and 50% sludge quantity. The oil obtained using the Soxhlet method at 70 °C, 1:4 ratio of date seeds to n-hexane solvent and 5 h reaction time was 16% of the date seed mass (79% biodiesel and 9% glycerine). Therefore, the resultant effect from the main findings indicated that the study supports the investigation of the possibility of exploiting date seeds in the production of biogas, biodiesel and bio-fertiliser.

“…W technice tej siarka zawarta w próbkach przeprowadzana jest w SO 2 , chociaż można mieć wątpliwości, czy związki nieorganiczne siarki, jak np. siarczany, są, w warunkach oznaczania, ilościowo przekształcane w ditlenek siarki [12]. Duże znaczenie w analizie próbek produktów naftowych ma spektrometria fluorescencji rentgenowskiej, jednakże należy wspomnieć o ograniczeniu wynikającym z efektów matrycowych spowodowanych obecnością związków zawierających tlen.…”

W artykule opisano obecnie stosowane znormalizowane metody rutynowego oznaczania siarki w paliwach i biokomponentach paliw. Przedstawiono także najnowsze badania dotyczące oznaczania siarki technikami spektrometrii atomowej, zwracając uwagę na dokładność i precyzję oraz ograniczenie niekorzystnych czynników mających wpływ na jakość wyników analitycznych. Wybór technik spektrometrii atomowej podyktowany był możliwością uzyskania niskich granic oznaczalności oraz wyników charakteryzujących się dobrą precyzją. Wydaje się, że techniki te powinny zostać wykorzystane w większym stopniu przy opracowywaniu nowych metod znormalizowanych oznaczania tego pierwiastka. Słowa kluczowe: oznaczanie siarki, paliwa ciekłe, biokomponenty paliw, spektrometria atomowa. Development of methods for the determination of sulfur in fuels and fuel components by atomic spectrometry techniques The article describes the currently used standardized methods for the routine determination of sulphur in fuels and in biocomponents of fuels. It also describes recent research on the determination of sulphur with the use of atomic spectrometry techniques, paying attention to the accuracy and precision of the determinations, and the reduction of adverse factors affecting the quality of the analytical results. The selection of the atomic spectrometry techniques was dictated because of the ability to obtain low detection limits and results characterized by good precision. It seems that these techniques should be used to a greater extent in the development of novel standardized methods for the determination of this element.
