Combined discrete nebulization and microextraction process for molybdenum determination by flame atomic absorption spectrometry (FAAS).

Speciation of Chromium in Water Samples after Dispersive Liquid-Liquid Microextraction, and Detection by Means of High-Resolution Continuum Source Atomic Absorption Spectrometry

“…Oviedo et al 28 achieved analytical calibration curves by performing continuous and discrete nebulization of Mo in an aqueous and organic medium. The ratio of angular coefficients of analytical calibration curves of samples in an organic medium obtained by discrete and continuous nebulization was around 10, displaying an increased sensitiveness level.…”

Vortex-assisted dispersive liquid–liquid microextraction for the determination of molybdenum in plants by inductively coupled plasma optical emission spectrometry

“…5 A strategy based on the use of vortex-assisted solidied organic drop (VA-SOFDME) microextraction combined with FAAS using discrete nebulization was proposed by Oviedo et al 5 for the determination of Mo in corn roots and leaves. The use of discrete injection for Mo determination in various samples was further investigated by Oviedo et al, 14 and it was demonstrated that this procedure is sensitive and efficient for the determination of Mo in situations in which a low sample volume is available and the sample consumption by the chosen determination technique is elevated.…”
