A novel vortex assisted dispersive solid phase extraction of some trace elements in essential oils and fish oil

Trace cadmium determination in lake water matrix by flame atomic absorption spectrometry after manganese ferrite magnetic nanoparticles‐based dispersive solid phase extraction

“…The mixing period is equally important because it determines the shortest analysis time within which the most efficient and precise extraction output would be achieved. [ 35 ] The true effect of mixing on extraction output was further examined by comparing the results of the different mixing periods to the results obtained for a similar extraction performed without mixing. All four tested mixing periods recorded average absorbance values that were at least 1.3 times higher than the average absorbance value without mixing.…”

“…This short period of mixing is similar to the 10 s optimum period reported by Tokay et al for the determination of cadmium and other metals using a dispersive solid phase extraction method. [35]…”

Ionic liquid assisted extraction induced by emulsion breaking for extraction of trace metals in diesel, gasoline and kerosene prior to ICP-OES analysis

“…Inductively coupled plasma (ICP) based instruments are well-documented for the determination of multielement in various matrices [ 11 , 12 ]. The most standard and easily available ICP techniques are inductively coupled plasma-optical emission spectroscopy (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS) [ 13 , 14 ].…”

“…Therefore, complexed matrices like fuels require sample preparation to convert them to aqueous phase [ [16] , [17] , [18] ]. Moreover, some of the metals in fuel oils are in trace levels (ppb-ppt) and require preconcentration step [ 12 ]. The most popular extraction and preconcentration methods reported for determination of metal ions in fuel oils are solid phase extraction (SPE) and liquid-liquid extraction (LLE) [ [19] , [20] , [21] , [22] , [23] , [24] ].…”
