Feasibility of sulfur determination in diesel oil by inductively coupled plasma optical emission spectrometry after microwave-induced combustion using flame retardant

Rozwój metod oznaczania siarki w paliwach i w komponentach paliw technikami spektrometrii atomowej

“…Oznaczanie pierwiastków śladowych w FAME przeprowadzano również na drodze rozcieńczenia estrów etanolem lub 1-propanolem [5] [6]. Spalanie próbki oleju napędowego zachodzi w zamkniętym naczyniu kwarcowym wypełnionym tlenem oraz kwasem azotowym(V), pełniącym funkcję roztworu pochłaniającego.…”

Development and Evaluation of a Novel Sulphur Analysis Method

“…The ICP was used for the determination of sulphur at a wavelength of 180.669 nm [13] with operating parameters given in Table I. …”

“…MIC operates in a similar manner to the bomb based on basic operating principles [3], [8], [12].The method showed a relative high efficiency [13] with multiple element extractions [3].This method is also preferred for samples that are difficult to digest or if volatile solids are to be preserved [14]due to its ability to handle acids as absorbing solutions, unlike the bomb [8], [15]. But the method also pose to be dangerous for the oxidation of organic fuels [11].…”

Microwave-induced combustion for petroleum coke digestion: a promising sample preparation strategy for subsequent elemental determination

“…This method is based on the combustion of the sample, in general rich in carbon, in the presence of a rich oxygen atmosphere, where the sample combustion was induced by the microwave radiation. [26][27][28][29][30] Since the combustion is performed in a closed system, aer digestion, analytes were quantitatively absorbed in a suitable absorbing solution and analyte losses are negligible, including volatile elements. 26,27,31,32 Contrarily to other combustion methods, MIC conveniently incorporates an optional reux step aer digestion by the continuous application of microwave radiation that signicantly improves analyte recovery.…”
