“…There were several absorption lines, which were reported to be the most sensitive lines (257.593; 257.958; 258.056) for sulfur determination. 27 Dittrich et al 28 determined sulfur at 469.413 nm using the normal atmospheric argon-a microwave-induced plasma method, and at 383.73 nm (S2 molecular band) using a glow discharge in the furnace nonthermal excitation spectrometry/molecular nonthermal excitation spectrometry method based on the emissions of S atoms, S + ions, S2 and CS molecules using sulfate.…”

“…The wavelength at 258.056 nm was not used because of the fact that a potential overlap was reported with the Fe lines. 27 Therefore, 257.958 nm was applied in the all apricot and grape samples.…”

“…When GF was used, stable and volatile carbon compounds could be formed before the measurement, decreasing the formation of the CS molecule in the gaseous phase; however, sulfur in crude oil could be determined using this technique. Resano and Flórez [17] investigated the potential of direct solid sample analysis for sulfur monitoring in different certified reference materials using Pd nanoparticles in combination with Ru as a permanent modifier. Mior et al [18] described a procedure for the determination of sulfur in coal with Ru as permanent modifier using direct solid sample analysis in a GF.…”

“…As PdNPs, por outro lado, já apresentaram resultados satisfatórios para geração da molécula CS para determinação de enxofre em diesel e amostras sólidas [138,241]. Portanto, uma solução foi preparada como descrita na Seção 4.2.2.2 e encontrou-se um valor ótimo de 5 μg de PdNPs para aplicação em amostras sólidas.…”
